Construction Note C000011 Master Feed Announcements

The pages provide Atom Site Feed entries for making the following announcements in the Numbering Peano site feed:

• C000011B: Test Announcement.  This entry is advanced (given a new number) and added to the current feed as the most-recent entry. This will cause a warning entry to be seen as the latest content of the feed.

• C000011C: Standby Announcement.  This page is pre-advanced and added in place of the current feed.  It accomplishes two things.  It makes a "Please Stand By" entry available as its only content.  It makes a valid feed file for access even if it is not recognized as a new change, so that feed subscribers will not encounter a corrupted feed file.

• C000011D: All-Clear Announcement.  This entry is advanced (given a new number) and added to the current feed (not the standby announcement, usually) to declare a test condition as completed.  This is also a manual entry into an existing feed.

The reason for advancing the identity and the title of the entries is so subscribers will not confuse a test announcement and the ensuing all-clear announcement as being updates of previous announcements.  It is less critical that the standby announcements be kept unique, and it is done for consistency.

Because standby announcements are set up to be applied quickly, without any preparation, they are incremented after use, not before.  A standby announcement is always "hot" and ready to be applied.

If there become multiple feeds on this site, there will need to be a separate set of master feed announcements for each one.  That is because entries are identified with particular feeds to ensure they are recognized.  [Whether this is the case for the test and all-clear cases remains to be seen.  That will be tested before we have to address the multiple feeds case.]

These pages provide the grounding for corresponding XML documents used to insert announcements in feeds and to replace the feed suddenly to prevent unexpected access of feed subscribers to corrupted material.  A  Job Jar is set up for the development required here.
