Hi Pablo,
Thanks, but no, that doesn’t work.
Sorry, Matthias, that was my fault. After replying and asking you to test, I started a new thread where I discovered that PDF/UA files were missing proper PDF/UA tagging. It couldn’t work.
Acrobat reads the document by just warning that the page is empty. While the report comes back mostly ok.
I’m afraid the report isn’t that useful for us at the current stage of tagging development.
The tag report list that lists all accessibility tags identifies the figure as <NonStruct> with information PathPathPathPathPathPath.
I had no idea, but I have read in the source (lines 217-218 from strc-tag.lmt) that figures (and mpgraphics) are tagged as "NonStruct" (as many other things). I think it is pretty consistent to tag them as "Figure". As for the information "PathPathPathPathPathPath", I cannot find such a string either as pure text (not even case-insensitive "ath") or as hex string (https://opensource.adobe.com/dc-acrobat-sdk-docs/pdfstandards/PDF32000_2008....). But I admit I have to be doing something wrong. Since you work with math, I also think that formula (line 221 from the same file) should be tagged as Formula. I’m happy to help debugging ConTeXt and investigating accesibility, but Hans has the last word on how this is going to be implemented in ConTeXt. Since there are many issues that have to be fixed (or decided) first, let’s wait until Hans replies. Many thanks for your help, Pablo
