Unsupported calendars #74

Closed ElizabethGow closed 5 years ago

ElizabethGow commented 5 years ago

Hello I've recently uploaded records for two of our Persian manuscripts which are dated using the Samvat calendar. I encoded these as follows:

<origDate calendar="#Hindu" when="1845">Samvat 1902 (1845 CE)</origDate>

However, despite the "when" attribute being given in the Gregorian calendar, the century isn't being indexed properly, and they come up as "Date in unsupported calendar".

Is there a fix for this other than just using calendar="#Gregorian"?

Thanks Elizabeth

The problem with unsupported calendars is that it isn't clear whether their when attributes had been converted to the Gregorian calendar, as per the TEI standard. About half the Hijri-qamari ones hadn't, so I batch converted those, but I didn't have time to research and convert all the less common calendars ("Coptic-EoM", "Alexandrian", "AM", "Other", etc.)

There were only five origDate elements in all the Fihrist collections which had a calendar of "#Hindu", now seven with your new ones, and they all appear to have the same roughly 57-year offset as your example, so I've added "#Hindu" to the list of supported calendars. And re-indexed, so your new records should now be included in the "19th Century" option in the Century filter.
