#  2.2 Data set description

Each data set that will be collected, generated or processed within the
project will be shortly described; the description shall include the following
elements:

  * The nature of the data set; 

  

  * Whether the data is associated with a scientific publication; 

  

  * Information on the existence of similar data sets; 

  

  * Possibility of reuse and integration with other data sets; 

  

  * If data is collected from other sources, the origin will also be provided. 

  

#  2.3 Data sharing

The coordinator, along with all the work package leaders, will define how data
will be shared and made public; more specifically the access procedures, the
embargo periods, the necessary software and tools to enable the re-use of all
data sets that will be generated, collected or processed during the project.
If one specific data set cannot be shared, the reasons will be mentioned
(potential reasons can be ethical, intellectual property, commercial, privacy
related, security related).

#  2.4 Archiving and preservation

The Consortium has discussed and decided upon the procedures to be employed to
ensure the long-term preservation of data sets. The Database/Repository that
will be employed for the preservation of data is Zenodo, hosted by CERN,
https://zenodo.org. Moreover, in order to contribute to the outreach
activities and dissemination of knowledge, the Consortium is planning to
create a dedicated Wiki pages with open databases/libraries of metal-organic
precursors and physical properties of piezoelectric materials.

#  Data sets

The Consortium has discussed the type of data that will be generated by the
research activity and what standards are going to be employed concerning
metadata, naming conventions, clear version numbers, software needed to access
the generated data, its interoperability, reusability and storage.

##  Metadata

The Beneficiaries, while performing the research activity in the framework of
the project, will describe and document the generated data employing the best
practices in their specific scientific field. The information will include
metadata such as, but might not be limited to depending on the type of
research:

  * Operational conditions of vibrational energy harvesters in the cars, including temperature and its gradients, vibrations, mechanical chocks, working atmosphere, etc. 

  

  * Physical and chemical properties of metal-organic precursors of alkali metals, Nb, and Ta including chemical and thermal stability, vapour pressure, evaporation temperature, vapour pressure, oligomerization, crystal structure, evaporation and decomposition temperatures, melting point, thermo-gravimetric data, differential scanning calorimetry, IR spectra, NMR data, solubility. 

  

  * Physical properties of lead-free piezoelectric materials (crystals, ceramics, thin films and nanomaterials) including piezoelectric, dielectric, and elastic constants, structural and morphogical data. 

  

All data sets will be presented with keywords, time/date and other info
relative to the specific experiment that might be deemed appropriate to be
shared.

##  Naming conventions & Employed standards

The following naming conventions and software standards will be employed in
the generation of the datasets, should different standards be necessary, this
Data Management Plan will be updated.

Naming conventions:

  * IEEE convention for the description of the piezoelectric material orientation and related physical constants, described by tensors. Matrix notation will be used for the tensors defined in orthogonal XYZ setting. XYZ setting will be defined according to the principal symmetry elements of the structure. 

  

  * Crystal structure and crystallographic orientations will be named according to the International Crystallographic convention. 

  

  * IUPAC convention will be used for the names of the metal-organic and organic compounds. 

  

  * SI system will be used for the units of the physical and chemical properties. 

  

Data standards and necessary software to access the generated data:

  * Description of data will be presented in PDF files. Any web browser will be able to open the generated data. 

  

  * Raw data will be given in txt or dat files, which can be opened by any software for the data treatment (Exel, Spreadsheet, Origin, Kaleidagraph, Matlab, etc.) Version numbers: the latest updated reference will be only provided, the date of updating will be indicated. 

  

##  Reusability and Interoperability

Data generated by the project will have to be scrutinised by the Consortium
that will discuss whether or not it is the case to publish it on the public
domain. Some data might be object of patents, in that case it will not be made
available until a patent request is filed or data is officially published.

With regards to the Interoperability and Reusability of data, metadata will be
made available for reuse with demand to be properly referenced. Moreover, as
stated above, common-use data standards will be employed to allow easy access.

##  Data Security

The Consortium has decided that data will be stored independently by each
beneficiary, no common recovery facility will be put in place.
