- Depends if they do the maps at regular intervals. Each area coordinator,
- while having standards to meet, might not always do the maps on a regular
- cycle. When I first sent in my map entry, it took six months for the new
- maps to come out. (I believe it was due to a change in the area project
- coordinator.) If they don't mind getting 6 entries per site for each
- map the put out (read that as 6 month of entries) and they are able to
- sort through them to find the most recent, fine. (I mention the sorting
- through them... probably only as a poke at your comment about the UUCP
- mapping coord. having to send out messages to each system... of course
- automation exists for both of those problems.... no offense meant... it's
- just late.)

- I'd say, maybe two or three mapping periods of no entries from a site before
- that site is deleted... just in case of any unforseen problems somewhere.

-
- As stated above... depends upon if the maps are done at regular intervals
- or not.

- OK, You've converted me. As for a CRON mailing of a pre-prepared site
- entry, that should be no problem on ANY uucp system. The automatic
- configuration is a different story, but that does not seem like it needs
- to be a requirement in order for the CRON mailing to work.

- You know... here we're talking about uucp... I just plumb didn't think

-
- Whatever method comes about... (will it be fixed?) as long as there is
- some KNOWN standard that can be implemented by most (99%?) of the sites
- in the project, thats fine with me.
-
- If the standard is a monthly CRON job, then a subset of standards could
- cover manualy-written-entries, CRON-written-entries, and lest we forget,
- the proxy-written-entries: The entries written by a service provider on
- behalf of a subscribing system. Who would be responsible in a case like
- that. The service provider, or the site manager. Which site should the
- entry come from. [Yikes, This would be more of a problem in my proposal
- for a polled map than it would for a CRONed map.]
-
- Are there any Mapping Project Managers (didn't have to use the SciFi term)
- out there with any comments?
