The data's explanation for INS is: Define an inserted text. INS has two standard attributes: Cite and DateTime. The cite value is a URL that points to another document that explains why the new text was inserted, a datetime value that specifies the date and time the text was inserted, and the format is Yyyy-mm-ddthh:mm:sstzd, where:
YYYY = 4-digit number for year (as 2008)
MM = 2 digits for month (such as 01,02,... 12)
DD = 2-bit number representing day (such as 01,02,... 31)
HH = 2 digits for hours (such as 01,02,... 24)
MM = 2 is a number that represents minutes (such as 01,02,... 30L
SS = 2 is the number of seconds (such as 01,02,... 30L
TZD = time Zone indicator
If the modified time is: May 28, 2008 21:05:00
Then according to Greenwich Mean Time DateTime's writing is: 2008-05-28t21:05:00z, according to Beijing Times is written: 2008-05-28t21:05:00+08:00. Because Beijing time is 8 hours earlier than Greenwich Standard Time.
So what is inserting a text? As the name suggests, it means inserting a new text into the original document. When using ins, we usually use a different del tag to define the deleted text in the document.
For example, a word news: "5.12 China Wenchuan occurred 7.8 magnitude earthquake." Now after the expert survey is revised to level 8, then you can use INS to insert new text to modify this sentence:
5.12 China Wenchuan occurrence <del cite= "; Datetime= "2008-05-18t19:08:00+08:00" >7.8</del> <ins cite= "; Datetime= "2008-05-18t19:08:00+08:00" >8.0</ins> magnitude earthquake
After modification:
5.12 China Wenchuan 7.8 8 magnitude earthquake
The cite and datetime values explain the reason for the modification and the time date.
Another example: "Warehouse existing 200 tents", today's goods have left 100 top:
Warehouse extant <del datetime= "2008-05-18t19:08:00+08:00" >200</del> <ins datetime= "2008-05-18t19:08:00+08:00" >100</ins> Top Tent
After modification:
Warehouse existing 200 100 Tents
The above 2 examples of using Del and INS give us a clear idea of when the document was modified, why it was modified, and when it was modified.
