When dealing with high level metadata (aka context metadata) the best place to find it is in the external catalogs and registries.

With this task, we should create strategy and a priority list for the registries we want to watch and the way we want to link the metadata found to an origin.

registries:

• fsf.directory
• wikidata
• libraries.io
• http://ascl.net/
• swhMath

packages managers:

• http://repo1.maven.org/maven2/ for Maven packages,
• npmjs.com for NPM packages

note: libraries.io already tracks this packages
