Both of those sound very interesting to me!
Also, putting the End-of-Year date at the top is interesting, too.
I certainly agree that the End-Of-Year date is a useful place to container for annual Objectives.
Since I like to generalize everything as much as possible and I find Patterns quite useful in that regard, I’ve also taken the view that Start-Of-Year date is a useful place to accumulate Complete Tasks and their summary reports. After all, people are generally aware of what the current Date is, so it’s easy for them to distinguish the Accomplishments and Plans for a year as we progress through it. In fact, I’ve even generalized the concept of the time period to recognize the natural nestings of all of the components of Mcdy-mm-dd
mm:ss (basically ISO UTS)

Another example of my use of tags to index into the person dimension of TheArray? (that obviously needs some housekeeping since it return more than 25 bookmarks) is… http://delicious.com/HansWobbe/~lionK. Enjoy! 
Now that GPS receivers are common, I can easily get the coordinates of my current location (in Natural Area Code, decimal latitude-longitude, or UTM coordinates), find the corresponding point on a map, and tell others how to return to this location later.
Alas, there are many other, more difficult problems involved in addresses and mapping. Would one of the map wiki listed at http://wikiindex.org/Category:Maps be a good place to discuss those problems and possible solutions?
Thanks for posting this comment, David!
I’d be happy to engage further on this topic at just about any location what so ever. Since I am trying to PostWhereTheyRead? in order to find other activities I can contribute to, and since WikiIndex seems relatively active I’d be happy to use that site. If you think you’d prefer a more quiet environment for formative thoughts, we can use either of our Oddmuse Bliki(s).
Lately I’ve been using Amplify to post snippets of content from many sites. This automatically generates Tweets and DelIcioUs? bookmarks, which in turn generate RssFeed(s), so most of my activity is becoming widely distributed across many diverse sites. Many people I collaborate with are now asking me to share a specific tag that encodes Topic+GroupTimeperiod… values. The result is that we can use delicious almost like a relational database of destination URLs. Its almost what you are looking for, as defined by your Wiki:DavidCary’s page “I’m building a data store…” section.
overly abstract meta-discussion
When I stumble across something that I think is a Big Problem (in any field), I find it productive to
Alas, (b) has not been as successful as I had hoped. Out of the 5588 wiki in the index, I can usually find one or two that has a narrow focus that seems to include my pet problem du jour. But after I post to that wiki, I often discover that it is nearly a ghost town, with only one or two people active, and those particular people are so hyperfocused on some even more narrow sub-field that they don’t really have a lot to say about my question. Ah well – after I putting my thoughts down in tangible form and clarifying what the problem is and how I would recognize a solution, that often helps me think more clearly about it, even if I don’t get any feedback.
And, of course, sometimes I do get extremely useful feedback, even if it is merely a single sentence “There’s an entire mailing list dedicated to that subject at [some address]”.
specific details
The WikiIndex is pretty active, but WikiIndex may not be the best place to discuss time and place. I suspect people exist that have spent more time pondering location in formation and how to combine maps and time-sensitive information than you and I put together. In fact, the evidence suggests that there are so many of them that they have started at least a dozen wiki that I know about – listed at http://wikiindex.org/category:map – and quite likely several others. (Alas, far too many of those wiki are now offline).
Please go to http://wiki.gis.com/ and post a couple of paragraphs about this problem and ask where are the people interested in this sort of problem. I am tempted to go ahead and post there on your behalf, but I suspect that something would get lost in translation.
Maybe, a “showondate” feature can be useful too, for advanced dates. --JuanmaMP
I’ve found the use of future dates such as “showondate”(s) very useful. In my case, though, Calandars, Reminders and “in-boxes” quickly became very elaborate and quite personal. As a result, I’ve built most of these functions into my TiddlyWiki systems. Now that TiddlySpace? is becoming an accepted way of sharing MicroContent tiddlers, I’m beginning to consider ways of sharing more of the infrastructure.
