The VLO's importer, search configuration and web application are published under GPL-3.0, with instructions for deploying a full instance. CLARIN ERIC, a European research infrastructure consortium governed by its member countries and set up to operate on a non-economic basis, runs it as a public service with no paid tier.

  Listed under "Active European Research Infrastructure Consortia (ERICs)": "CLARIN, the pan-European Common Language Resources and Technology Infrastructure, makes digital language resources available to scholars and researchers of all disciplines".

The VLO publishes no count of searches or visitors, and activity on its code repository says nothing about use of the portal. No reading was recorded.

  Release notes through "VLO 4.15.0 (September 2026)"; no usage figure.

The VLO searches metadata that language-resource centers publish and it harvests, and the resources themselves stay with those centers. It holds and serves no data of its own, so like Masader it is a catalog that points to its providers.

  Abstract: "a metadata-based portal for language resources"; "We describe the metadata harvesting process, based on OAI-PMH, and the conversion from several formats ... to their CMDI counterpart profiles."
