We've carefully selected our indexing sources based on various criteria, such as openness, structured, machine-readable metadata, stability of the data model, minimum standards for data completeness and quality, and the availability of options to automatically extract the data, for example via APIs or bulk data downloads. This ensures that we can ingest new, quality content quickly.

Unfortunately, at this time, we are not able to index any content not already available in our indexing sources. Please consider depositing your metadata in one of them to benefit from our automated indexing.
