Trismegistos [http://www.trismegistos.org; abbreviated as TM], is an interdisciplinary platform covering metadata about texts from the Ancient World (800 BC - AD 800). Its database currently contains information about provenance, dating and the archival context, geographic and prosopographical attestations in these texts and references to both classical authors and modern editors. All of this information (and more) is openly accessible for all of our users on the TM website. Now TM is expanding its role as data curator and service provider with the launch of the new Data Services portal (https://www.trismegistos.org/dataservices), currently focused on the metadata about TM Texts and Places (https://www.trismegistos.org/geo). By using the digital tools such as the TM APIs, web applications can be enriched with validated linked open data from the TM database. The provided endpoints can be used in combination with other web services to create interactive, feature-rich content due to the light-weight, customizable JSON-responses. By calling the endpoint with a valid Trismegistos Geo ID (e.g., Alexandria = TM Geo 100; http://www.trismegistos.org/place/100), users can download a JSON file or directly parse the content of the call in GeoJSON format. This ID can also be used to retrieve URIs linking to more information about a TM Place via the GeoRelations portal (https://www.trismegistos.org/dataservices/georelations/documentation), providing a total of over 33,000 indexed URIs from 19 partner websites. The TexRelations portal (https://www.trismegistos.org/dataservices/texrelations/documentation) similarly offers information on the textual level, by offering JSON, XML or JSON-URI based responses. This endpoint successfully links over 1 million online resources from 79 partner websites. The lightweight responses can be used by anyone, using tools such as FileMaker, POSTMAN, Python scripts or customizable JavaScript solutions. By providing reliable and easy-to-use endpoints TM wants to provide stable IDs to existing projects and help researchers by pointing them towards other resources of scientific knowledge. In doing so, hopefully more links from new partners will be added to the different TM portals (such as TM Texts and Places) and linked to a TM ID, creating a carefully curated network of Ancient World Linked Open Data.
