This document discusses using Schema.org to describe marine data and link ocean data on the web. It provides background on linked data and Schema.org. It describes work done by various organizations to apply Schema.org to describe datasets, organizations, projects, and other marine data. This includes developing schemas and cataloging various types of marine data. Future work is discussed, such as supporting tabular data and linking to other vocabularies for different data types.

Editor's Notes
- Publishing: Done in collaboration with the facilities. Focused mostly on schema.org type Dataset with an eye toward future extension work. Vocabulary work now at ESIP Indexing (summoning) Go based code “gleaner (summoner)” built that pulls the JSON-LD based schema.org from resources. Driven by sitemap files. Indexing (milling) Go based code “gleaner (miller)” is a set of patterns for adding different indexing (“milling”) workflows to work on the summoned code. Main ones were spatial, test and graph. Also have SHACL, Tika pipelines and alternative indexing and other miller options in the works. Serving APIs and sample interface at https://geodex.org using indexes from millers.
