OSIS? 2.0.1 User's Manual - Web services are running on AMBIB

for weekly dates, and for named times of day (such as used in many prayer books). There
<strong>are</strong> 3 standard date formats; the prefixes that identify them <strong>are</strong> reserved, and may not be
redefined via the refSysId attribute of any work element:
• yearly:yyyy-mm-ddThh.mm.ss
Any number of fields may be left off from the right end; for example, if the
seconds <strong>are</strong> dropped (along with the preceding colon), the time refers to the entire
minute specified; if the entire time section is left off (along with the preceding
"T"), the string refers to the entire day.
The year must always have 4 digits. However, the year may be entirely omitted to
indicate dates that apply to any year, such as in a book of 365 daily readings.
To indicates years before the common era, add an underscore ("_") before the first
digit of the year (immediately following the colon). A hyphen would be
preferable, but it is already in use to indicate ranges in osisRefs.
The entire date/time string (possibly including a leading underscore) may be
preceded by "~", indicating that the time is approximate. No means is provided to
express just how approximate a time may be.
• weekly:n
When readings or other materials <strong>are</strong> specified as being for particular days of the
week, this form must be used. The 'n' value may range from 1 to 7; 1 indicates
Monday, in accordance with ISO 8601:2000.
As an alternative to quantitative times, a small set of named times is provided, which can
be specified in place of the entire (post-"T") time section (the "T" itself remains). For
example:
yearly:06-04T~(Vespers)
would be the identifier for a prayer, reading, or other work to be used at Vespers on June
4 of any year. The named times (which <strong>are</strong> case-sensitive) include: Vigils, Matins, Lauds,
Terce, Sext, None, Vespers, Compline; Sunrise, Sunset; Morning, Afternoon, Evening,
Night; AM, PM; Fajr, Zuhr, _Asr, Maghhrib, _Isha, Lail, Dzuha, _Id.
Some works will be primarily organized by dates and times: for example, lectionaries,
daily devotionals, prayer books, historical time lines, etc. In such works, use the osisID
attribute to identify the retrievable portions; the value should the the applicable time in
one of the formats just shown.
Typically, such works <strong>are</strong> organized in chgronological order of the times specified;
however, <strong>OSIS</strong> does not impose that requirement.
