description: Gravitational microlensing is a powerful tool for probing the inner structure of distant quasars. In this context, we have obtained spectropolarimetric observations of the two images of the broad absorption line (BAL) quasar SDSSJ081830.46+060138.0 (J0818+0601) at redshift $z \simeq$ 2.35. We first show that J0818+0601 is actually gravitationally lensed, and not a binary quasar. A strong absorption system detected at $z$ = 1.0065$\pm$0.0002 is possibly due to the lensing galaxy. Microlensing is observed in one image and it magnifies the emission lines, the continuum, and the BALs differently. By disentangling the part of the spectrum that is microlensed from the part that is not microlensed, we unveil two sources of continuum that must be spatially separated: a compact one, which is microlensed, and an extended one, which is not microlensed and contributes to two thirds of the total continuum emission. J0818+0601 is the second BAL quasar in which an extended source of rest-frame ultraviolet continuum is found. We also find that the images are differently polarized, suggesting that the two continua might be differently polarized. Our analysis provides constraints on the BAL flow. In particular, we find that the outflow is seen with a nonzero onset velocity, and stratified according to ionization.

description: Even for common NLP tasks, sufficient supervision is not available in many languages -- morphological tagging is no exception. In the work presented here, we explore a transfer learning scheme, whereby we train character-level recurrent neural taggers to predict morphological taggings for high-resource languages and low-resource languages together. Learning joint character representations among multiple related languages successfully enables knowledge transfer from the high-resource languages to the low-resource ones, improving accuracy by up to 30% over a monolingual model.

Improving Operations Using Standards and Metrics: Self-Assessment of Long-Term Preservation Practices at FSD
Creators: name: Kleemola, Mari
Publisher: name: Zenodo
Year: 2012

description: Preserving digital data is a challenge. For the outcome to be successful, many organisational and practical issues need to be in place. The Finnish Social Science Data Archive (FSD, http://www.fsd.uta.fi/) is dedicated to support the life cycle of digital research data in social sciences. It is therefore critical that FSD's operations and procedures are up-to-date and consistent with relevant standards and best practices. The key standard for long term preservation of digital data is the Open Archival Information System (OAIS) Reference Model (ISO14721:2003). This presentation will explore FSD's conformance to OAIS and describe how FSD's functions map to the seven OAIS functions (ingest, archival storage, data management, administration, preservation planning, access and common services), with special attention to ingest and access. We will also discuss the process and results of a self-assessment that was conducted analysing FSD policies, plans and procedures within the framework of the Audit and Certification of Trustworthy Digital Repositories (TDR) Checklist (CCSDS 652.0-M-1). We will summarise the weaknesses, risks and strengths identified, discuss the use of the TDR metrics and analyse how adopting standards and best practices could facilitate co-operation and collaborative partnerships.

description: The New Zealand Emissions Trading Scheme (NZ ETS) was launched in 2008 following more than a decade of policy deliberation on how emission pricing could support New Zealand’s contribution to international climate change mitigation efforts. Reflecting the unique emissions and economic profile of New Zealand, New Zealand’s regulatory culture, and lessons learned from earlier environmental markets, including within New Zealand, it pioneered many ETS features. Examples include design for coverage of all economic sectors and major greenhouse gases (GHGs); an upstream point of obligation in the energy sectors with opt-in by major downstream users; output-based free allocation to eligible emissions-intensive, trade-exposed activities where the firms involved were not necessarily points of obligation; zero free allocation to energy-sector participants in recognition of the fact that they could pass on emission prices; and a monitoring, reporting and verification system based on self-assessment with audits and penalties to deter non-compliance. From 2008 to mid-2015, the NZ ETS operated without a cap on domestic emissions but instead was nested within the international Kyoto Protocol cap, enabled by buy-and-sell linkages to the Kyoto market. Legislative amendments to moderate the system’s impact combined with an oversupply of units in the international market contributed to low domestic emission prices in recent years, and policy uncertainty has obscured the system’s long-term price signal. While the NZ ETS may have had a small impact on the forestry sector, officials have found no evidence that it has contributed significantly to domestic mitigation. From 2012 through to mid-2015, participants predominantly met their NZ ETS obligations by purchasing overseas Kyoto units at low cost. The NZ ETS did enable the government to meet New Zealand’s international obligations for the first commitment period of the Kyoto Protocol (2008–2012) with a substantial unit surplus. In 2015, the NZ ETS delinked from the Kyoto market and it currently operates as a domestic-only system. The government is reviewing the system in 2016. The system requires changes to align with New Zealand’s Intended Nationally Determined Contribution (INDC) under the 2015 Paris Agreement and to effectively support New Zealand’s decarbonisation pathway.

description: In Schloss Dagstuhl and in Gothenburg before EDDI 2011, ontology engineers and experts from the social, behavioral and economic sciences developed an ontology of both DDI Codebook and Lifecycle and implemented a rendering of DDI instances to RDF (Resource Description Framework). The main goals associated with the design process of the DDI ontology were to reuse widely adopted and accepted ontologies like DC or SKOS and also to define meaningful relationships to the RDF Data Cube vocabulary. Now, organizations have the possibility to publish their DDI data and meta-data in RDF and link it with many other datasets from the Linked Open Data (LOD) cloud. As a consequence, a huge amount of related DDI instances can be discovered, queried, connected, and harmonized. Only the semantic combination of DDI data as well as meta-data of several organizations will enable derivations of even surprising and not imaginable implicit knowledge out of explicitly stated pieces of information.

description: By employing the technique of enlargement of filtrations, we demonstrate how to incorporate information about the future trend of the stochastic interest rate process into a financial model. By modeling the interest rate as an affine diffusion process, we obtain explicit formulas for the additional expected logarithmic utility in solving the optimal portfolio problem. We begin by solving the problem when the additional information directly refers to the interest rate process, and then extend the analysis to the case where the information relates to the values of an underlying Markov chain. The dynamics of this chain may depend on anticipated market information, jump at predefined epochs, and modulate the parameters of the stochastic interest rate process. The theoretical study is then complemented by an illustrative numerical analysis.

description: The time evolution of angular momentum and surface rotation of massive stars is strongly influenced by fossil magnetic fields via magnetic braking. We present a new module containing a simple, comprehensive implementation of such a field at the surface of a massive star within the Modules for Experiments in Stellar Astrophysics (MESA) software instrument. We test two limiting scenarios for magnetic braking: distributing the angular momentum loss throughout the star in the first case, and restricting the angular momentum loss to a surface reservoir in the second case. We perform a systematic investigation of the rotational evolution using a grid of OB star models with surface magnetic fields ($M_\star=5-60$ M$_\odot$, $Ω/Ω_{\rm crit} =0.2-1.0$, $B_{\rm p} =1-20$ kG). We then employ a representative grid of B-type star models ($M_\star=5, 10, 15$ M$_\odot$, $Ω/Ω_{\rm crit} =0.2 , 0.5, 0.8$, $B_{\rm p} = 1, 3 ,10, 30$ kG) to compare to the results of a recent self-consistent analysis of the sample of known magnetic B-type stars. We infer that magnetic massive stars arrive at the zero age main sequence with a range of rotation rates, rather than with one common value. In particular, some stars are required to have close-to-critical rotation at the ZAMS. However, magnetic braking yields surface rotation rates converging to a common low value, making it difficult to infer the initial rotation rates of evolved, slowly-rotating stars.

Ensembles and experiments in classical and quantum physics

description: A philosophically consistent axiomatic approach to classical and quantum mechanics is given. The approach realizes a strong formal implementation of Bohr's correspondence principle. In all instances, classical and quantum concepts are fully parallel: the same general theory has a classical realization and a quantum realization. Extending the `probability via expectation' approach of Whittle to noncommuting quantities, this paper defines quantities, ensembles, and experiments as mathematical concepts and shows how to model complementarity, uncertainty, probability, nonlocality and dynamics in these terms. The approach carries no connotation of unlimited repeatability; hence it can be applied to unique systems such as the universe. Consistent experiments provide an elegant solution to the reality problem, confirming the insistence of the orthodox Copenhagen interpretation on that there is nothing but ensembles, while avoiding its elusive reality picture. The weak law of large numbers explains the emergence of classical properties for macroscopic systems.

Renormalization of the periodic Anderson model: an alternative analytical approach to heavy Fermion behavior

description: In this paper a recently developed projector-based renormalization method (PRM) for many-particle Hamiltonians is applied to the periodic Anderson model (PAM) with the aim to describe heavy Fermion behavior. In this method high-energetic excitation operators instead of high energetic states are eliminated. We arrive at an effective Hamiltonian for a quasi-free system which consists of two non-interacting heavy-quasiparticle bands. The resulting renormalization equations for the parameters of the Hamiltonian are valid for large as well as small degeneracy $ν_f$ of the angular momentum. An expansion in $1/ν_f$ is avoided. Within an additional approximation which adapts the idea of a fixed renormalized \textit{f} level $\tildeε_{f}$, we obtain coupled equations for $\tildeε_{f}$ and the averaged \textit{f} occupation $$. These equations resemble to a certain extent those of the usual slave boson mean-field (SB) treatment. In particular, for large $ν_f$ the results for the PRM and the SB approach agree perfectly whereas considerable differences are found for small $ν_f$.

description: Gaussian latent variable models are a key class of Bayesian hierarchical models with applications in many fields. Performing Bayesian inference on such models can be challenging as Markov chain Monte Carlo algorithms struggle with the geometry of the resulting posterior distribution and can be prohibitively slow. An alternative is to use a Laplace approximation to marginalize out the latent Gaussian variables and then integrate out the remaining hyperparameters using dynamic Hamiltonian Monte Carlo, a gradient-based Markov chain Monte Carlo sampler. To implement this scheme efficiently, we derive a novel adjoint method that propagates the minimal information needed to construct the gradient of the approximate marginal likelihood. This strategy yields a scalable differentiation method that is orders of magnitude faster than state of the art differentiation techniques when the hyperparameters are high dimensional. We prototype the method in the probabilistic programming framework Stan and test the utility of the embedded Laplace approximation on several models, including one where the dimension of the hyperparameter is $\sim$6,000. Depending on the cases, the benefits can include an alleviation of the geometric pathologies that frustrate Hamiltonian Monte Carlo and a dramatic speed-up.

description: We study the dynamics of an asymmetric simple exclusion process with open boundaries and local interactions using a pair approximation which generalizes the 2-node cluster mean field theory and the Markov chain approach to kinetics and shares with these approaches the property of reproducing exact results for the bulk current-density relation and the steady state phase diagrams. We find that the relaxation rate exhibits a dynamical transition, with no static counterpart, analogous to that found without interactions. Remarkably, for some values of the model's parameters, we find 2 dynamical transitions in the same low density phase. We study the dynamics of relaxation to the steady state on both sides of these transitions and make an attempt at providing a physical interpretation for this phenomenon. Results from numerical approaches and a modified Domain Wall Theory confirm the picture provided by the pair approximation.

description: We introduce the notion of $N$-reflection equation which provides a large generalization of the usual classical reflection equation describing integrable boundary conditions. The latter is recovered as a special example of the $N=2$ case. The basic theory is established and illustrated with several examples of solutions of the $N$-reflection equation associated to the rational and trigonometric $r$-matrices. A central result is the construction of a Poisson algebra associated to a non skew-symmetric $r$-matrix whose form is specified by a solution of the $N$-reflection equation. Generating functions of quantities in involution can be identified within this Poisson algebra. As an application, we construct new classical Gaudin-type Hamiltonians, particular cases of which are Gaudin Hamiltonians of $BC_L$-type .

description: We study the association between fiscal policy and subjective wellbeing using fiscal data on 35 countries and 130 country-years, combined with over 170,000 people’s subjective wellbeing scores. While past research has found that ‘distortionary taxes’ (e.g. income taxes) are associated with slow growth relative to ‘non-distortionary’ taxes (GST/VAT), we find that distortionary taxes are associated with higher levels of subjective wellbeing than non-distortionary taxes. This relationship holds when we control for macro-economic variables and country fixed effects. If this relationship is causal, it would offer an explanation as to why governments pursue these policies even when they harm economic growth. We find that richer people’s subjective wellbeing is less harmed by indirect taxes than for people with lower incomes, while “unproductive expenditure” is associated with higher wellbeing for the middle class relative to others, possibly reflecting middle class capture. We see little evidence for differential effects of fiscal policy on people living in different sized settlements. Devolving a portion of expenditure to subnational government is associated with higher subjective wellbeing but devolving tax collection to subnational government is associated with monotonically lower subjective wellbeing.
A Church in the Wild : Recontextualizing the Backcountry as a Spiritual Landscape and the Shelter as Sacral Architecture
Creators: name: Mella, J. Patrick
Publisher: name: The University of British Columbia
Year: 2022

description: The term “wilderness” is difficult to define as its boundaries constantly shift and our perception of it just as grey. Typically depicted as rugged and untouched landscapes, its relationship to humans have changed overtime whether it was viewed as a place of danger and fear, a useless obstruction, or somewhat recently, a place of unspeakable beauty. Spirituality is also a constantly shifting notion, and just as vague. Many attribute it to solitude, nature, and solace often tied with religious beliefs. These beliefs and narratives were not a construction of a new world but rather a deconstruction, re-interpretation, and reconstruction of the existing one around us. Sacral architecture and structures were early examples of artifacts; traces of humanity acting as spiritual channels, a way to comprehend order in chaos through sensory input. Yet despite an increasingly secular and, arguably, non-religious society, wilderness landscapes continue to be spaces of contemplation and reflection. This poses a question for artifacts, and what they might entail when stripped down to their essence, as mediators between the human figure and the landscape. Is there value in embracing these human traces in the wild and how might that begin to define a different type of spirituality based on perception? This is a study of the spirituality found in the backcountry as experienced through the human scale, an exploration of our place in the world and a celebration of our capacities.

description: We test whether a single housing market exists across sixteen cities covering two countries, Australia and New Zealand. Distances between these cities are vastly greater than commuting distances. We define a single housing market as one in which a single stochastic trend describes the long run path of real house prices in all cities. A strong form single housing market occurs when an innovation to the stochastic trend affects house prices across all cities multiplicatively to an equal degree. A weak form occurs when an innovation to the stochastic trend affects house prices in all cities, but not to an equal degree. We find that the sixteen housing markets are characterised by a weak form single housing market. The dynamic structure of adjustment reveals three groups of cities. House price shocks are first reflected in the price dynamics of a leading group of Australian cities (including Melbourne and Sydney), then flow to a group of follower cities comprising peripheral Australian and major New Zealand cities, and then to a group of laggard cities within New Zealand. Our theoretical model demonstrates how a weak form single housing market may arise due to differences between cities in house price responses to land prices, migration responses to house prices and/or land price responses to migration flows.

description: To extend the discrete velocity method (DVM) and unified methods to more realistic boundary conditions, a Cercignani-Lampis (CL) boundary with different momentum and thermal energy accommodations is proposed and integrated into the DVM framework. By giving the macroscopic flux from the numerical quadrature of the incident molecular distribution, the reflected macroscopic flux can be obtained for the given accommodation coefficients. Then, an anisotropic Gaussian distribution can be found for the reflected molecules, whose parameters are determined by the calculated reflected macroscopic flux. These macroscopic flux and microscopic Gaussian distribution form a complete physical process for the reflected molecules. Furthermore, the CL boundary is integrated into the unified gas-kinetic scheme (UGKS), making it suitable for the simulation of both monatomic and diatomic gas flows, and it accommodates both the conventional Cartesian velocity space and the recently developed efficient unstructured velocity space. Moreover, this new GSI boundary is suitable for both explicit and implicit schemes, offering better performance for flow prediction. Finally, the performance of the new boundary is validated through a series of numerical tests covering a wide range of Knudsen and Mach numbers.

description: Spectral fingerprints of molecules are mostly accessible in the terahertz and mid-infrared ranges, such that efficient molecular-detection technologies rely on broadband coherent light sources at such frequencies. THz Quantum Cascade Lasers can achieve octave-spanning bandwidths. However, their tunability and wavelength selectivity is often constrained by the geometry of their cavity. The recently introduced Quantum Cascade Random Lasers represent alternative sources of THz light, in which random scattering provides the required field confinement. The random resonator geometry greatly relaxes wavelength selectivity, thus producing radiation that is both spectrally broadband and collimated in the far-field. Yet, the intrinsic randomness of these devices' spectral emission strongly restricts the scope of their potential applications. In this work, we demonstrate the all-optical adaptive control and tuning of Quantum Cascade Random Lasers. The specificity of our random-laser sources is exploited to locally modify the system's permittivity with a near-infrared (NIR) laser beam and thereby substantially reconfigure the distribution of disorder. Using a spatial light modulator combined with an optimization procedure, the NIR illumination is spatially modulated to reshape the spectral emission and transform the initially multimode laser into a single mode source, which could be harnessed to perform self-referenced spectroscopic measurements. Moreover, we show that local NIR perturbations can be used to sense linear and nonlinear interactions amongst modes in the near field. Our work points the way towards the design of broadly tunable THz sources with greatly relaxed fabrication constraints.

Dark Energy Constraints from Weak Lensing Cross-Correlation Cosmography
Creators: name: Bernstein, G. M.

Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We present a method to implement the idea of Jain & Taylor to constrain cosmological parameters with weak gravitational lensing. Photometric redshift information on foreground galaxies is used to produce templates of the mass structure at foreground slices z_\ell, and the predicted distortion field is cross-correlated with the measured shapes of sources at redshift z_s. The variation of the cross-correlation with z_s depends purely on ratios of angular diameter distances. We propose a formalism for such an analysis that makes use of all foreground-background redshift pairs, and derive the Fisher uncertainties on the dark energy parameters that would result from such a survey. Surveys from the proposed SNAP satellite or the LSST observatory could constrain the dark energy equation of state to 0.01 f_sky^{-1/2} in w_0 and 0.035 f_sky^{-1/2} in w_a after application of a practical prior on Ω_m. Advantages of this method over power-spectrum measurements are that it is unaffected by residual PSF distortions, is not limited by sample-variance, and can use non-linear mass structures to constrain cosmology. The signal is, however, very small, amounting to a change of a few parts in 10^3 of the lensing distortion. The calibration of lensing distortion must be independent of redshift to comparable levels, and photometric redshifts must be similarly free of bias. Both of these tasks require substantial advance over the present state of the art, but we discuss how such accurate calibrations might be achieved using internal consistency tests. Elimination of redshift bias would require spectroscopic redshifts of 10^4-10^5 high redshift galaxies.

description: We introduce DAYENU, a linear, spectral filter for HI intensity mapping that achieves the desirable foreground mitigation and error minimization properties of inverse co-variance weighting with minimal modeling of the underlying data. Beyond 21 cm power-spectrum estimation, our filter is suitable for any analysis where high dynamic-range removal of spectrally smooth foregrounds in irregularly (or regularly) sampled data is required, something required by many other intensity mapping techniques. Our filtering matrix is diagonalized by Discrete Prolate Spheroidal Sequences which are an optimal basis to model band-limited foregrounds in 21 cm intensity mapping experiments in the sense that they maximally concentrate power within a finite region of Fourier space. We show that DAYENU enables the access of large-scale line-of-sight modes that are inaccessible to tapered DFT estimators. Since these modes have the largest SNRs, DAYENU significantly increases the sensitivity of 21 cm analyses over tapered Fourier transforms. Slight modifications allow us to use DAYENU as a linear replacement for iterative delay CLEANing (DAYENUREST). We refer readers to the Code section at the end of this paper for links to examples and code.

description: Optimal flight gate assignment is a highly relevant optimization problem from airport management. Among others, an important goal is the minimization of the total transit time of the passengers. The corresponding objective function is quadratic in the binary decision variables encoding the flight-to-gate assignment. Hence, it is a quadratic assignment problem being hard to solve in general. In this work we investigate the solvability of this problem with a D-Wave quantum annealer. These machines are optimizers for quadratic unconstrained optimization problems (QUBO). Therefore the flight gate assignment problem seems to be well suited for these machines. We use real world data from a mid-sized German airport as well as simulation based data to extract typical instances small enough to be amenable to the D-Wave machine. In order to mitigate precision problems, we employ bin packing on the passenger numbers to reduce the precision requirements of the extracted instances. We find that, for the instances we investigated, the bin packing has little effect on the solution quality. Hence, we were able to solve small problem instances extracted from real data with the D-Wave 2000Q quantum annealer.

description: In Meidt et al. (2018), we showed that gas kinematics on the scale of individual molecular clouds are not dominated by self-gravity but also track a component that originates with orbital motion in the potential of the host galaxy. This agrees with observed cloud line widths, which show systematic variations from virial motions with environment, pointing at the influence of the galaxy potential. In this paper, we hypothesize that these motions act to slow down the collapse of gas and so help regulate star formation. Extending the results of Meidt et al. (2018), we derive a dynamical collapse timescale that approaches the free-fall time only once the gas has fully decoupled from the galactic potential. Using this timescale we make predictions for how the fraction of free-falling, strongly self-gravitating gas varies throughout the disks of star-forming galaxies. We also use this collapse timescale to predict variations in the molecular gas star formation efficiency, which is lowered from a maximum, feedback-regulated level in the presence of strong coupling to the galactic potential. Our model implies that gas can only decouple from the galaxy to collapse and efficiently form stars deep within clouds. We show that this naturally explains the observed drop in star formation rate per unit gas mass in the Milky Way's CMZ and other galaxy centers. The model for a galactic bottleneck to star formation also agrees well with resolved observations of dense gas and star formation in galaxy disks and the properties of local clouds.

description: In this article, a new model is proposed for the operation of microgrids (MGs) using optimal distribution feeder reconfiguration (DFR) and optimal generation scheduling (OGS). The distributed generation units, electric vehicles and demand response (DR) are modelled in the presented model. The DR programs consider load shifting, load curtailing and time-of-use programs. The proposed model is formulated as a mixed-integer second-order cone programming problem and solved by the GAMS software package. The total operating cost is taken into account as the objective function and several operational constraints are used in the optimization problem. The simulation results of the 33-bus MG are shown, where considering OGS along with DFR leads to a lower operating cost. In addition, the load shifting of a DR program can reduce the total operating cost by smoothing the load profile and reducing the cost of power purchases from the main grid.

description: Animal production accounts for 16% of international agri-food trade. The growing imbalance between supply and demand for animal products in Asian countries, where consumption is growing, particularly in China, stimulates trade for the benefit of the major exporting countries: the European Union (EU), the United States, New Zealand, Brazil and Australia. While this development offers trade opportunities for countries with a structural surplus, purchases fluctuate from year to year and price competition is very strong, despite the qualitative requirements of some countries. The EU, which has a positive trade balance in dairy products and pork, but a negative one (in monetary terms) in beef and poultry meat, is the world's largest exporter of animal products (with 22% of the extra-EU trade in 2016). This article analyses the evolution of trade in animal products using customs statistics data (BACI and COMEXT) from 2000 to 2016. It presents the evolution of international trade for different types of goods (dairy products, beef, pork, poultry meat) and highlights the trade trajectories (patterns) of the main net importing countries (China, Japan and Russia) and net exporting countries (India, Australia, New Zealand, Brazil, the United States and the EU).

description: The food retail sector in many developing countries is transforming with a rapid growth of modern supermarkets. Supermarkets are not only influencing how food is sold to consumers, but also how agricultural products are sourced from farmers. Especially for the procurement of fresh fruits and vegetables, supermarkets often contract farmers directly to ensure consistent, high-quality supply. Previous studies analyzed the effects of supermarket contracts on smallholder farmers’ income. However, most existing studies relied on cross-section data and focused on the estimation of average income effects. Possible implications for other dimensions of household welfare were hardly examined. We add to this literature by using panel data from smallholder vegetable farmers in Kenya and econometric models with household fixed effects to estimate average and heterogeneous treatment effects of supermarket contracts on income and multidimensional poverty. On average, supermarket contracts increase per capita income in smallholder farm households by 60\%. We also find significant reductions in income poverty and multidimensional poverty. Quantile regressions show that farmers in all income groups benefit, but richer households benefit more than poorer ones in absolute terms. On the other hand, supermarket contracts cause the strongest reductions in multidimensional deprivations among the poorest households.
Improved effective momentum approximation for quasielastic (e,e') scattering off highly charged nuclei

description: We address the problem of including Coulomb distortion effects in inclusive quasielastic (e,e') reactions using an improved version of the effective momentum approximation. Arguments are given that a simple modification of the effective momentum approximation, which is no longer applicable in its original form in the case of highly charged nuclei, leads to very good results. A comparison of the improved effective momentum method with exact calculations is given. A critical remark concerns recent experiments with inclusive quasielastic positron scattering.

Accessing DDI 3 as Linked Data - Colectica RDF Services
Creators: name: Smith, Dan
Publisher: name: Zenodo
Year: 2012

description: Linked Data represents an opportunity to publish the structured data of DDI 3 and publish it in a way that can be interlinked to become even more useful. Linked data makes use of existing web technologies standardized by the W3C such as HTTP and URIs and extends them to enable the machine actionability of web information. The DDI 3 has a very robust information model containing many relationships between metadata items. This can be seen through the DDI 3's use of references to enable reuse. This DDI model can also be represented in RDF. This paper examines why serializing DDI as RDF can be beneficial, how DDI 3 can be represented in RDF, stored in a repository, and queried using the standard SPARQL query language. An example of these concepts is demonstrated using Colectica RDF Services.
