Dear colleagues,
We are now opening discussion for week 3 about the metadata structure associated to each DOI to build a functional Global Information System. Again, let us focus the discussion on PGRFA only at this stage. The purpose of such metadata structure is to assist users and client applications to:
a) identify the PGRFA being registered with each new DOI (This week we can detailed the scope of the identifiers);
b) search for PGRFA during a discovery operation;
c) model PGRFA interactions through a minimum set of relation operators (This point was already anticipated during Week 1);
d) allow the registration of multiple targets associated to each DOI;
e) allow for association of existing identifiers. These can be local or global, permanent or not, but are commonly used by the entity owner to refer to the PGRFA like the “accession number”, for example, as discussed during the previous weeks.
f) be expressed in a metadata format that can be (or already is) mapped to some widely accepted standard such as RDF, DWC, Crop Ontology and so on.
Many of you already mentioned that the Multi-Crop Passport Descriptors V.2 could be a good starting point, but that there is the need for some extension in terms of relational operators, so we can further elaborate on this.
We look forward to this week’s discussion on this stimulating topic.
Thank you,
Regards,
Treaty Secretariat
