What can we do with metadata
Context
Other Metadata Infrastructures in our domain: IMDI, OLAC/DC, TEI
Problems: Inflexible: too many (IMDI) or too few (OLAC) fields Limited interoperability Problematic (unfamiliar) terminology for some sub-
communities. etc.
CLARIN Project - CMDI
Metadata infrastructure based on a
“Component Metadata Model” Aims
Flexibility Researcher should themselves decide what metadata fits their
needs Offer ready made metadata components Allow creation of new metadata components needed
Interoperability built-in Complete Infrastructure: software for editing, harvesting,
exploitation Compatibility with existing frameworks: OLAC, IMDI

Create metadata schema from selection of existing components. Allow creation of new components if they have references to ISOcat
Perform search/browsing on the metadata catalog using the ISO DCR and other concept registries and CLARIN relation registry
Metadata component profile was selected from metadata component registry
Metadata harvestingby OAI protocol
Metadata descriptions created
Current solution
What if you want to contribute metadata now? The CLARIN ad-hoc registry (800+ resources, 130+ tools) Provide IMDI or OLAC metadata Harvesting (metadata transport) via:
OAI protocol for OLAC records or provide static records XML harvesting for IMDI
Harvested metadata will be shown in a special CLARIN catalog.
Using the standard MPI/LAT catalog software and integrated in VLO specializations
Use & Create CMD components now
What if you are adventurous? CLARIN metadata toolkit allows to start creating metadata
components or use existing ones. We have an existing set of components derived from:
IMDI metadata for sessions IMDI catalog metadata
Small CLARIN NL project planned to test and report on this But you can try it too!
