Import HTML about standoff-properties-editor

[argimenes]

Thanks, my intention is to support HTML content in a few stages:

[1] To store the imported HTML as a zero-width annotation (this has now been written but not yet pushed). This allows HTML to be viewed in the document but does not allow the user to annotate the textual content of the imported HTML block

[2] To convert the imported HTML elements to matching stylistic annotations. The sanitize-html library would help establish the correctness and security of the HTML for this operation. The limitations of the approach would be that managing complex layout structures like DIVs, TABLEs, etc., could be complicated in standoff, as sibling order is crucial to the rendering, and this needs work in SPEEDy

[3] Another approach I am thinking through is to combine standoff annotation with embedded HTML ... should be fairly easy to import, but the export process will need to be carefully considered.

Thanks for feedback! Embedded HTML is another issue, I was looking for a way to convert existing documents to standoff-properties data format. I mostly use Markdown but HTML is more common and Markdown can be converted to HTML. The pandoc document converter gives a good summary of most common layout types among document formats (with pandoc you get import from dozens of document formats). Support of this would be enough:

• Inline elements
  • bold (b, strong), italic (i, em)
  • external links (a)
• Block elements
  • headings (h1, h2...)
  • paragraphs (p)
  • quotations (blockquote)

Support of more block elements (horizontal rule, lists, code blocks, tables) might be added later.
