The metadata in the Virtual Language Observatory is based on several sources. Therefore there is not a single way of correcting or updating the entries. To determine where a metadata record stems from and to update it, inspect the Corpus facet (for resources) or the contributor facet (for tools) and follow the instructions below.
1. CLARIN LRT inventory
If the corpus facet indicates "clarin", follow the following procedure to curate the metadata in the LRT inventory:
- Log in to the CLARIN LRT site via http://lrt.clarin.eu/user
- Go to http://lrt.clarin.eu/view_resources
- Click on the name of the Resource or Tool
- Click on the Edit tab
- Now change the metadata fields
- Click on the save button at the bottom of the page
2. CMDI or OLAC
For curation of metadata delivered in the CMDI or OLAC format (via OAI-PMH) no other steps need to be taken than changing the metadata in the originating repository. To find out information about it click on the open in original context link. As there are diverse repository systems providing their metadata a as CMDI or OLAC there is no unified way of making changes. However once adaptations are made in the original repository they will later on automatically be reflected in the VLO.
3. IMDI (corpus = mpiCorpora )
Use Arbil (http://www.lat-mpi.eu/tools/arbil) to download the metadata file, edit it and replace the old version in the archive with LAMUS (http://www.lat-mpi.eu/tools/lamus).
About the update interval
Please note that changes made as described above will not be immediately reflected into the VLO, as in general some manual synchronization steps need to be taken. For the CMDI and OLAC metadata it should take at most 2 days before the changes are visible in the VLO.
