Service Class 4: Metadata services
The possibility to build from the research products of PUNCH4NFDI a dynamic knowledge fabric is the next step. The definitions of their functionality and interfaces, prototype metadata schemes, data formats and published and interoperable digital research products using the full range of PUNCH4NFDI services are provided. The corresponding catalogue technology will be accessible for all interested users through the PUNCH-SDP.
4.1 The PUNCH digital Research Product: functionality and interfaces (D-TA4-WP1-4)
The development and definition of DRPs includes the establishment of functionality of how to logically connect all their elements. This comprises a unified description of interfaces and resources needed to execute a DRP for a successful analysis preservation policy. External containers and science platform products will be supported as well as developments in the other initiatives. PUNCH4NFDI will provide services to access, modify, and execute DRPs in cloud environments accessible to PUNCH4NFDI.
4.2 Published and interoperable Research Products (D-TA4-WP4-2/D-TA4-WP4-4)
PUNCH4NFDI will provide published and interoperable dynamic Research Products using the full range of PUNCH services, including combined analysis of datasets from different sources and experiments. Moreover working Research Product examples together with stored data and interoperable analysis workflows will be provided.
4.3 metadata schemes and data formats (D-TA4-WP2-1)
PUNCH4NFDI will define a prototype metadata scheme which covers the various data formats from the PUNCH community. This will include also a transformation of the different data (and metadata) formats in a prototype data format. Especially smaller communities will profit from this activity.
4.4 The PUNCH Research Product Database (D-TA4-WP1-1)
A central database for PUNCH4NFDI will be developed, which can run on distributed inatances and allows to access Research Products from outside sources. The catalogue will incorporate all necessary metadata from available document-, data-, code- repositories and registries across the PUNCH community. Entries in the catalogue will be described and organised using a common standard.
4.5 Open Research Catalogue (D-TA4-WP1-2)
Existing Research Products available in the PUNCH community will be ingested into an open research catalogue through a clearly defined submission process. This includes also the development of best practices for data publication. The research catalogue will enable researchers to publish Digital Research Products in a state that allows for re-execution of the code on local facilities as well as on the PUNCH Science Data Platform. Via the research catalogue it will be possible to interlink separated data silos using a unified access layer to metadata which complies with the FAIR principles.
