(20) Interoperability Issues . Standardization efforts . . . Semantic interoperability research . 15/17. XML Schemata and XSLT stylesheets have been specified (e.g. OAi-PMH) Common metadata formats are defined (e.g. Dublin Core, MARC21) Structural approaches (e.g. RDF/XML) Ontological Interoperability Subject of research in DL.
(21) Conclusions . . . . . 16/17. Search engines for grey literature are being widely deployed and represent a central information service in scholarly communication Institutional repositories gain momentum and become dominant over disciplinary repositories Standardized frameworks for distributed and federated document processing have been established Information interoperability has been achieved on the syntactic and structural/schematic level, whereas semantic interoperability remains a research issue CDSware implementing OAi-PMH, freely available (GNU/GPL).
