Create an ETL pipeline for LaTeX-based documents published as Lander landing pages. This is similar to the work done for reStructuredText-based technotes in
Because metadata for LaTeX documents is computed at build time from the source (i.e., it required a checked-out Git repo), it makes sense to publish a JSON-LD document at build time as well.
The choices are either to add the JSON-LD as a script tag in the landing page itself, or add a metadata.jsonld document alongside the HTML, but in a separate file.
Then an ETL pipeline run from lsst-projectmeta-kit itself would ingest this data and load it into MongoDB, as we're already doing for reStructuredText-based technotes.
