As part of my effort to facilitate the development of a successor to the current, somewhat jury-rigged system used to publish the Traceable Heraldic Art collection, I’ve been working on exporting the current data in a format that could be imported by someone developing a successor system.
You can now retrieve nearly all of the textual content of the collection via a series of JSON data files which are automatically rebuilt each time the site is updated.
The entries.json file (5.4 MB) contains one object for each illustration — charge, fur, field division, etc — including the name, description, attribution, and links to the associated SVG and PDF files.
The artists.json (16 KB) and sources.json (83 KB) files provide metadata associated with attributions, while the headings.json (1990 KB) and volumes.json (3 KB) files record the category structure used to group related entries together.
More work is required, but hopefully this is a step in the right direction.
