#  Introduction

This deliverable provides the RadioNet data management plan (DMP) version 1.0.

It is important to mention that the RadioNet project does not create data in
the true sense of the word. However, one of the activities is designed to
develop software for astronomical data. Thus some of the astronomical data
will be used in the development phase of the software testing.

This document outlines how the collected or created research data will be
managed during and after the RadioNet project. The DMP describes, which
standard and methodology will be followed for data collection and generation,
and whether and how the data will be available.

This document follows the template (ver. 3.0, 26.7.2016) provided by the
European Commission in the Participant Portal  1  .

#  1 Data Summary

The RadioNet project will generate software products for radio astronomy data
sets in the JRA RINGS (WP7). RINGS will generate reference data, both actual
data and simulations, from various facility sets (LOFAR, _e_ -Merlin, etc.).
The purpose of these data sets is the validation and verification of the
developed algorithms. The generated astronomical data will be in the common
formats, i.e. the MeasurementSet [see
_http://dx.doi.org/10.1016/j.ascom.2015.06.002_ ] and FITS images. If data
sets are already available then those will be reused. Otherwise, new
observations and simulations will be requested to generate a reference data
set. The software will reuse the CASA and CASACORE libraries. The origin of
the data are the radio astronomy facilities. The expected size of the data is
several TBytes to 1 PByte. Software will be of the order of several kloc.
After the lifetime of the project, the data sets will be kept available on
Github and maintained by the RINGS partners for any future improvements of the
algorithms. The main users of the results are radio astronomers.

#  2 FAIR data

##  2.1 Making data findable, including provisions for metadata

The data sets will be stored in the existing archives of the facilities.

The metadata standards and discovery from those facilities will be used.
Simulated data will be reproducible by the sets of parameters to generate
them. These parameters will be documented wherever the simulations are used.
Software products will be integrated in CASA/CASACORE and use the associated
discovery mechanisms. For the data products, we will follow the naming
conventions of the facilities. For the software products we will use the
naming conventions of CASA/CASACORE. The metadata in the archives of the
various facilities adequately describes all relevant parameters and keywords
for searching. For software products the search keywords are not applicable.
There will be no clear version numbers in case of the archives, as the
metadata contains timestamps that uniquely identify the observation data.
However, in case of the software – version numbers with the versioning schemes
of CASA/CASACORE will be followed. The metadata created for observations is
described in the Measurement Set standard [see reference above] and in the
FITS standard. The metadata associated with software products are the headers
in the code and the software documentation.

##  2.2 Making data openly accessible

The archives of all RadioNet facilities comply with the open standards
policies. All data will be available during and after the project´s lifetime.
Software products will become available as open source. The archives are
accessible via web interfaces, most of them complying with the Virtual
Observatory (VO) standards. The software products will be made accessible via
the CASA/CASACORE repository in Github.

Depending on the data size, the data is directly downloadable or is accessible
by interaction with the observatory staff. Where possible VO tools can be used
to access images. For software products, direct download from the repositories
will be available and do not require additional tooling.

The various archives have their own documentation about the software needed to
access the data. It is not necessary to include the relevant software, as all
tools are openly available. Data and the associated metadata will be stored in
the archives of the RadioNet facilities. Code implementing calibration
algorithms and the associated documentation will be integrated with the
CASA(-CORE) repositories. Both are open source and there are no restrictions
on use. An appropriate arrangement with the identified repository has been
explored. There is no need for a data access committee.

##  2.3 Making data interoperable

The data produced is stored in common formats and standards of the
astronomical communities and the software products will adhere to the
interoperability conventions of CASA/CASACORE, that is allowing data exchange
and re-use between researchers, institutions, organisations, countries, etc.
The Measurement Set and FITS standards will be used for data and metadata
vocabularies in order to make the data interoperable. The standard
vocabularies will be used for all data types present in the data set, to allow
inter-disciplinary interoperability. A use of uncommon or generated project
specific ontologies or vocabularies is not foreseen.

##  2.4 Increase data re-use (through clarifying licences)

Software products are published in the CASACORE repository under GNU General
Public License v3.0. Data products are subject to the data policies and
licenses of the RadioNet facilities (see Table 2.1). If new data is required,
the data will generally become available 1 year after the observation has
taken place (see also Table 2.1). No re-use of the data outside the radio
astronomy community is currently foreseen. However, the data is openly
accessible for third parties. The project will seek interaction with
industrial partners to investigate the reuse of the software products in other
domains. The data storage terms determined by the archive policy of the
facilities, which is commonly to store data indefinitely. There are no limits
foreseen to the reusability of software products delivered by RINGS. The data
quality is ascertained by the quality procedures of the facilities.

#  3 Allocation of resources

There are no costs required to make the data FAIR. The JRA RINGS leader will
be responsible for the data management. There is no need for plans for long-
term preservation, as they will be designed by the facilities and the
CASA/CASACORE collaboration partners

#  4 Data security

The data is secured according to the policies and arrangements of the RadioNet
facilities, which are publicly available (See table 2.1 for the address). They
assure a long-term preservations and curation of the data.

**5 Ethical aspects**

There are no ethical or legal issues that can have an impact on data sharing.

#  6 Other issues

The RadioNet JRA RINGS is using the data generated by RadioNet facilities,
which follow their own procedures for the data management. However, since the
RadioNet facilities follow the open policy procedure, no particular influence
on the FAIR is expected.
