1 1 Metadata Elements and Domain Groups - Keith G Jeffery

2 2 …. and now for something completely different….

3 3  Since RDA P2:  Recommendations (standards)  Software services  So the community can  Build, maintain, develop repositories to provide researcher access  Interoperate repositories in a domain  Interoperate across domains  A necessary recommendation is on metadata  Supported by software services RDA Purpose: a personal view

4 4  Since RDA P2:  Recommendations (standards)  Software services  So the community can  Build, maintain, develop better repositories to provide researcher access  Interoperate repositories in a domain  Interoperate across domains  A necessary recommendation is on metadata  Supported by software services RDA Purpose: a personal view

5 5  Domain researchers and ICT support/development people asking RDA Metadata Groups for recommendations on metadata  For use within their individual repository  For (interoperability) use within a domain  For interoperability use across domains  One example is ICOS  Carbon cycle and greenhouse gases Requirement

6 6  Discovery  Finding data, software, people (users), resources (computers, storage, instrumentation);  Relevance to purpose (initial assessment)  Contextualisation  Appropriate for the purpose (assessment)  Quality (syntax, semantics – including multilinguality)  Recording activity (who did what, when, where to which)  Connecting data to Software / Environment / resources  Schema level (syntax, semantics – including multiliguality) Metadata Used for

7 7 Metadata / other groups Plan Involves not only metadata groups but all RDA Evolved since P2 Washington DC  Use cases into repository (DICIG)  Standards into MSDWG directory/catalog (MSDWG  MSCWG)  Analyse for commonalities and differences (MIG)  Propose canonical metadata ‘packages’ for ‘purposes’ (MIG)  Validation of ‘packages’ (domain groups)  Provision of convertors  This is a resource problem!  Move to standardisation of ‘packages’ (RDA)

8 8 Open Data: Purposing the elements  Unique Identifier (for later use including citation)  Location (URL)  Description  Keywords (terms)  Temporal coordinates  Spatial coordinates  Originator (organisation(s) / person(s))  Project  Facility / equipment  Quality  Availability (licence, persistence)  Provenance  Citations  Related publications (white or grey)  Related software  Schema  Medium / format ©Keith G Jeffery et alCRIS14 Rome May 2014 8 discovery context detailed

9 9  Many (most) of the elements are not simple single valued  e.g. Originator (organisation(s) / person(s))  Many are multilingual  So we need structured metadata (not flat metadata)  Base entities (exist in real world)  Linking entities (relationships between base entities) with role and temporal duration But Note

Other Notes: IVOA Standards found here: http://www.ivoa.net/Documents http://www.ivoa.net/Documents The IVOA RM standard uses Dublin Core as a basis; consequently, the metadata is assuming a resource-based metadata model Our resource metadata model is not exclusively data-centric: in addition to describing data collections, it is also used to describe organizations, services, registries, standards.
