Data Feed Example

When specifying a date-time value in an attribute for an RSS feed, use this format:

YYYY-MM-DDThh:mm:sstz[+|-offset]

Where:

YYYY is the year (4 digits).

MM is the month (2 digits).

DD is the day (2 digits).

T is a literal character used as a separator.

hh is the hour (2 digits in 24-hour time designation).

mm is the minute (2 digits).

ss is the second (2 digits).

tz is an RFC822 time zone. RFC822 supports UT, GMT, and Z for universal time, and the following North American time zones: EST, EDT, CST, CDT, MST, MDT, PST, and PDT.

offset is the difference between the local time zone and GMT in the format hh:mm.

All of these examples are correct:

2002-06-03T16:06:05.00GMT
2002-06-03T16:06:05.00UT
2002-06-03T16:06:05.00PDT
2002-06-03T16:06:05.00GMT-07:00
2002-06-03T16:06:05.00JST
2002-06-03T16:06:05.00GMT+09:00
2002-06-03T16:06:05.00Z

As shown by these date-time examples, you can specify numeric offsets in the date-time string. Thus, Greenwich Mean Time can be specified as either GMT or GMT+00:00 or UT or Z, and Eastern Standard Time can be specified as either EST or GMT-05:00.

Repositories that dispatch data feeds must explicitly specify the content type to avoid the filtering overhead required by Oracle SES to detect the content type. See the <contentLink> and <content> elements in the example.

The following example shows a data feed containing three documents.
