• The VLO is a search tool that can be used to find relevant data by searching through metadata
• Searching can be done various facets, e.g. date, location, genre, collection
• The primary users are researchers working in a specific domain for which the set of facets is optimised.
• Different instances for specific domains can be provided
• Community data managers can use the VLO to make their data available to a larger audience
• B2FIND is a general metadata catalogue for non-specific researchers an easier to use, but less specific tool to find resources
• B2FIND to be used for CLARIN collection level metadata and not for individual resource metadata

• The VCR is a repository of collection metadata
• In the VCR virtual collections are defined that contain links to resources stored in other repositories
• Researchers  can use the VCR to group data into virtual collections of their choosing and make these collections  findable and citable
• Researchers can seamlessly access virtual collection content

• The LR switchboard can provide a set of relevant tools for specific data types

• It is not meant as a stand-alone service, but as a feature that can be integrated  with other services.

• Users can use this feature to find relevant tools for processing data objects directly from within the data discovery or hosting service.

• Tool and service providers can make their tools available via the LR switchboard by specifying its features (tool metadata).

Integration of B2NOTE with the VLO.

B2NOTE can be used from the VLO as an added discovery mechanism using semantic annotations in addition to metadata. Users can add semantic annotations and search for them.
