This short guideline document how services affiliated with Text+ may be described in the SSH Open Marketplace. With its portfolio, Text+ as an NFDI consortium for language- and text-based research data addresses various tasks within scientific research data management. A significant part of this portfolio consists of services that are provided by the participating data and competence centers as well as developments within Text+. These services – with the term "service" defined broadly – are to be provided through the Text+ portal in a simple, understandable, and contextualized manner. The approach chosen by Text+ for making services visible therefore relies on: SSH Open Marketplace as the actual provisioning and curation site of the descriptive metadata of the services, Text+ Registry as the delivering service in the Text+ portal, which harvests the metadata from the SSH Open Marketplace, And the Text+ portal itself as the presentation layer on top of the registry. Overall, both Marketplace and Registry remain as machine-harvestable sources, with the Marketplace being the authoritative source.
