Under the hood it’s not XML-TEI — it’s a relational/data-pipeline approach, with article boundaries, sections, contributors, cross-references, and source-page provenance all reconstructed into structured records. The text itself is public domain, but I haven’t released a bulk structured export yet.
People asking for dataset access has definitely been one of the themes of this thread. I’m taking that seriously. If I do expose it, I’d want to do it in a form that preserves the structure and doesn't just dump plain text.
