new instance for layout analysis

[eroux]

We should launch a new instance for layout analysis, which means:

• [x] a new systemd service
• [x] a new configuration file
• [x] a new recipe
• [x] a new nginx configuration on the server + a new ssl certificate
• [x] a new set of tags that can be associated with an image

I'm not sure what the tags will be @eric86y pointed out https://journal.digitalmedievalist.org/article/id/8073/ which can be a good example.

I think there should be at least:

• text area
• illustration
• margin
• header/footer
• perhaps string holes or pseudo-string holes would be also useful?

also we should define how illustrations work, perhaps in an annotation manual. Do they tag the illustration + the caption, or do we create 2 different tags? Also, what exactly do we tag as the margin? do we count the frame in the text area? do we tag stamps? Here's an interesting example we should annotate:

Sounds good! We did a bit of testing/research and agreed to start with 5 basic classes like the ones you listed + an "other" class. At the end of next week we'll review what was done and revise the tagset as needed.

Portrait/Book format:

1. text area
2. illustration
3. caption
4. margin
5. header
6. footer
7. hole
8. other

Landscape/Pecha format:

1. text area
2. illustration
3. caption
4. margin
5. hole
6. other

also, what images do you want to tag? the entirety of the BDRC images? If so we need to understand how to create a recipe for that (I'm actually not quite sure how to do that... because I guess we don't want to just annotate them in alphabetical order?)

just created a recipe for the layout Analysis and below image is how it looks for now.

looks good

for modern book formats, I think better tags would be:

text area margin header footer footnote area other

for Chinese book format we can tag the registers as text areas
