Non Linear Hyphens

[jpmoreux]

Describing hyphen running on 2 pages or between main text flow and footnotes block is undeterministic.

Example:
left page: one hyphen in last footnote: "Victor-"
right page: one hyphen in main text flow ("Font-") and 2nd part of page 194 hyphen ("Hugo")

In this example, ALTO markup could let one think that String "Font-" is the first part of the hyphen (HypPart1), and String "Hugo" the second part (HypPart2). In such a case, a validation tool on hyphens consistency will fail at doing its job.

These ALTO files were produced during an EPUB+ALTO digitization program. EPUB format needs to identify footnotes and consequently, export of hyphens in ALTO files are logically correct but "unclear" in the ALTO "context".

The SUBS_CONTENT attribute does distinguish between "Fontanes" and "Victor-Hugo", would checking SUBS_CONTENT be an option for a validation tool?
