A researcher wants to find relevant resources by the available metadata, using keywords or other search dimensions (facets) such as date, location, language, format, etc. to use in their work. Many of such resources are available through the CLARIN infrastructure.

A linguist wants to be able to find (software) tools that can be used to process the data that they have found. For instance, they want to find a tokenizer for the Dutch language.

A repository manager wants to make a repository and its resources findable for researchers. There may be various forms of resources which may have anywhere from no metadata to well-defined elaborate metadata based on specific schema.

A community manager wants to make some language technology tools findable for researchers. The tools have minimal metadata.

A researcher wants to be able to access the content of a resource that he has found using a search engine or other means. He does not want to need separate credentials to access resource and prefers to use his institute’s credentials for access.

A researcher wants to manage a group of for him relevant resources (not limited to a single existing collection or site) that are relevant for her in a way that they can be are easily findable, accessible, and citable.

• The VLO is a search tool that can be used to find relevant data by searching the metadata.
• The search can be done using in various facets, e.g. date, location, genre, collection.
• The primary users are researchers, mainly linguists.
• Community data managers can use the VLO to make their data available to a larger audience.
• B2FIND is for non-specific researchers a more easy an easier to use, but less specific tool to find resources

• 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 and repository managers can
• Researchers  can use the VCR to group their data into virtual collections of their choosing and make these collections this data is findable  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 explicitly not meant only as a stand-alone service, but as a function feature that can be integrated with to  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).
