Metadata ecosystem
Links to statements created outside of the professional library communityOther communities: archives, museums,
publishers, etc.Machine-generated statements
Statistical and semantic inferencingUsers
No test of truth for a single statementProvenance: who said that?
From here ...Legacy statements useful for new stuff
AuthoritiesOld expressions, new manifestations
Lots of duplicate legacy recordsSo lots of duplicate statements after conversion
De-duplicate with “same-as” links
Need appropriate representations of metadata attributes and relationshipsISBD, FRBR/AD/SAD, RDA, UNIMARC, MO/ADS, ... Where is MARC21?
... to there (and back again?)
Choice of types of statementdct:titleisbd:P1004 (has title proper)frbr:P3020 (has title of the manifestation)rda:titleManifestation
Can re-use instead of creating new typesCan develop same-as linksRequires inter-agency, international
collaboration ...
