Ethiopic Calendar formatted dates

PietroLiuzzo commented 4 years ago

There is at the moment no proper visualization of dates. While we ought to provide standard gregorian, we could also provide Ethiopic calendar

Describe the solution you'd like How to format the date for Ethiopic calendar

Describe alternatives you've considered None yet

SophiaD-M commented 4 years ago

There are apps for this taks: https://www.metaappz.com/Ethiopian_Date_Converter/Default.aspx (this is a random one, there might be better) Maybe its possible to implement it to BM? Or to give the link?

PietroLiuzzo commented 4 years ago

thanks, I will look at how they format dates in their code

thea-m commented 4 years ago

Might this issue be somehow related to the fact that the calendar attributes list in the schema is currently commented out? Can it be de-commented?

PietroLiuzzo commented 4 years ago

calendar section in schema is not commented out any more

PietroLiuzzo commented 4 years ago

perhaps @smaugustine has something to suggest here? a js solution? I remember your calendar...

smaugustine commented 4 years ago

@PietroLiuzzo, I was just about to write something to you regarding this. The issue with most available code is that it is not concerned with pre-Gregorian dates (that is to say, virtually every existing calendar converter will produce incorrect dates for those before 1582). Also, there is little code already available to aid with other important dating calculations (evangelist year, Easter computus, etc.).

This is the app I finally put together some months ago (see here for the relevant JS, which includes both calendar conversion and Computus-related functions). I'm happy to discuss sometime in more detail the methods of calculation and how to adapt the scripts.

There's also a little bit more here (put together based on a specific request I received).

smaugustine commented 3 years ago

@thea-m, @PietroLiuzzo, @eu-genia, is there a means for encoding date+month combinations? I've been looking for examples but haven't really seen any.

If we had some sort of explicit encoding (like date="22" month="1" or date="22.01" for 22 Maskaram), we could add this to the visualization (<time data-ethiopian-month="1" data-ethiopian-date="2">) then have a tooltip populated by jQuery with the Gregorian/Julian equivalent like:

$('time[data-ethiopian-month]').each(function() {
  var westernDate = toWestern($(this).data('ethiopian-month'), $(this).data('ethiopian-date'));
  ⋮
})

The only hangup, aside from making sure that all the dates are encoded clearly, is also including an estimated year/century, particularly for distinguishing Julian and Gregorian conversions, but also dealing with the gradual shifting of the calendars. The suggested dating of the manuscript, for example, could be used to infer an approximate date.

smaugustine commented 3 years ago

As a follow-up on years/eras/etc., I think that there are too many considerations to allow for automatic conversion of years based on information from colophons, but that it may be worthwhile to provide a tool whereby an editor/user can input the available information (e.g. ṭǝntyon, abaqte, indiction) and then the tool suggests possible years.

I could put a page like this together, if it seems worthwhile. Some months ago I put this together, so there would already be a base to work from. (To be sure, more things could be added, like the evangelist, the date of Easter, the reigning monarch, etc., and these would be fairly easy to include).

thea-m commented 3 years ago

Hi @smaugustine ! There is the possibility of encoding day and month hidden in the guidelines https://betamasaheft.eu/Guidelines/?id=dates with, for example <date ref="ethiocal:Maskaram1">. It has not been used very often, mainly for encoding (recurring) commemoration dates, not a certain day in history. You can have a look here https://betamasaheft.eu/calendar.html

PietroLiuzzo commented 3 years ago

In addition to the system we use for recurring days and months correctly pointed out by @thea-m, please additionally refer to the guidelines for dates. we use att.datable attributes which are quite explicit https://www.tei-c.org/release/doc/tei-p5-doc/de/html/CO.html#CONADA

PietroLiuzzo commented 3 years ago

Also, If I may share a slight concern, I do not terribly like the idea of inferring dates or approximation, when this is after all already most the time implied in the encoding of a date in the manuscript description. it would add layers of approximation to layers of approximation.

smaugustine commented 3 years ago

The issue is that there's no way, really, to convert a date like "6 Sane" without having some sense of the year being discussed: this year it's June 13, in 1708 it was June 11, in 1408 it was May 31. So in contexts where the manuscript/work only gives the month and day, there is no way, really, to make a meaningful conversion without providing a window of a few centuries. It doesn't need to be a precise year, that's why usually conversions give a window of 2 days, but this still requires a choice of which era to use.

smaugustine commented 3 years ago

For now, putting aside more problematic cases, it would be possible to start with conversions of precise dates where the year, month, and day are known. However these might be encoded in TEI, my suggestion is to use data- attributes in the HTML (presumably a <time> element, but could be a <span> or anything else) and do conversions client-side.

As I suggested above, I can provide the functions in JS for doing the conversions and the relevant functions in jQuery, but the sort of XSLT that it sounds like would be required to set things up is something I don't think I could do.

As a rough sketch of my suggestion:

<span>
  <xsl:attribute name="data-year">…</xsl:attribute>
  ⋮
</span>

<span data-year="1434" data-month="sane" data-day="6">Sane 6</span>
⋮
<script>
$('span[data-year]').each(function(){
  var ethiopianDate = { day: $(this).data('day'), month: $(this).data('month'), year: $(this).data('year') };
  var westernDate = toWestern(ethiopianDate); // May 31, 1442
  // put westernDate into a tooltip or other form of display
});
</script>

PietroLiuzzo commented 3 years ago

The issue is that there's no way, really, to convert a date like "6 Sane" without having some sense of the year being discussed: this year it's June 13, in 1708 it was June 11, in 1408 it was May 31.

I do not think that these where intended to be converted while they may be aligned with a specific calendaric date as shown by @thea-m . This allows grouping recurrences of commemorations for example. The text of the issue did not help in figuring this out and I am sorry it has misled you. I think we can however offer better support, by providing a link to a specific search in the calendar view in the same type of box we are building below.

so, we are speaking of dates only and I think @SophiaD-M was actually referring to things like the info box of person records where we have gregorian dates which could be displayed as dates in the current Ethiopic calendar. I think that is reasonable and if I misunderstood @SophiaD-M can clarify.

your example seems to me to involve a conversion from Ethiopic calendar to western calendar, I think we need a bit more to be able to decide the direction of the conversion, i.e., the js needs to know what type of calendar is used, so that it can decide what to do. when this information is absent I think it should assume gregorian/western.

<span data-calendar="ethiopic" data-year="1434" data-month="sane" data-day="6">Sane 6</span>

which I can easily construct in the xslt. in facts, when a @calendar is present in the <date> a small box with a table is produced already just to give visibility to the information in the element. I think I would put the conversion there, in the case of a converstion from a calendar different from "western" to western. the same I can add to the dates without @calendar and add there the explicit information it is gregorian, so that you can build the w3 tooltip on that. what do you think?

to summarize

[ ] <date> and datable elements like <birth>, <death>, <floruit>will produce in XSLT a <span> with @data-* including calendar. this will be produced by the XSLT / XQuery producing the views by @PietroLiuzzo
[ ] for dates with @ref only, recurring dates in the form of day and month only, a box will produce a link to the filtered search. this will be produced by the XSLT / XQuery producing the views by @PietroLiuzzo
[ ] for full dates @smaugustine JS will produce a. content for a line in a table in the case of a @calendar different from the standard b. a tooltip with the converted date in Ethiopian calendar in case of standard dates
[ ] a module with the js produced by @smaugustine will be linked where appropriate or included in existing js modules, eventually accompanied by related css, by @PietroLiuzzo

how does it sound? thanks

smaugustine commented 3 years ago

This is a sensible approach.

The Julian/Gregorian distinction isn't so much of an issue to deal with, Gregorian is used for JDN >= 2299160.5 (Ṭǝqǝmt 8, 1575) otherwise Julian (<= Ṭǝqǝmt 7, 1575).

The one unaddressed issue is the year. Are Ethiopian dates encoded with years according to ʿĀmata Śǝggāwe (or ʿĀmata ʿĀlam) or another system? It's not a problem to convert these, as long as it's consistent/clear.

PietroLiuzzo commented 3 years ago

I have no clue about this distinction, but I think it would be nice to provide both when converting from western, if they are relevant.

smaugustine commented 3 years ago

So here is a demo (using the current js file on the branch): https://jsfiddle.net/_smaugustine/0jLkr5o7/33/.

Currently it is a function (convertDate()) that converts a given date and returns a string.

Note that it:

Returns a readable string (tbh I don't see the advantage of a table for users)
Converts specific dates as well as month+year combos
Allows for mixed dates using an Ethiopian month and an Anno Domini year (this occurs a lot in the Encyclopaedia and elsewhere)

The examples in the demo are:

Ethiopian date to Western [Julian] (18/4/1437 => 14/12/1444)
Ethiopian date with Anno Domini year (21/5/1439AD => 16/1/1439)
Ethiopian month+year (12/1427 => 8/1435)
Ethiopian date with ʿĀmata ʿĀlam year (27/10/6916AA => 21/6/1424)
Western (Gregorian) date to Ethiopian (22/1/1901 => 14/5/1893)

PietroLiuzzo commented 3 years ago

Thanks @smaugustine ! I have added to the branch the XSLT to produce the desired attributes for this JS, in the branch. I have then added the calling function copied from the fiddle to the module adding those js script to the page views, always on the branch. because values are varied there is not much one can rely upon, I have made one time element for each attribute present. The values in the js for @calendar do not match the values we assign in the guidelines, perhaps this can be updated? https://betamasaheft.eu/Guidelines/?id=date

This is now integrated in the new app. The branch is old and my modifications to the XSLT obsolete, so I opted for copying in the js file (unmodified) from there and paste it in the main branch, I hope you do not mind @smaugustine . For each date-like element an icon will be provided, hovering on which a tooltip is displayed which attempts the dateConversion on each <time> element which can be extracted from available attribute values.

after

If there is also a calendar information and additional attributes, the calendar icon will follow.
