There are RSS feeds for content-driven websites but some of these offer XML

What exactly are the implications for this?

Here are definitions I Googled:

Definitions of XML Feed on the Web:
* A simplified version of HTML that allows data to be sent to search
engines in the format that they can interpret.
www.awsp.com/search-engine-glossary.html
* Also referred to as Trusted Feed. A process where web pages are fed into the search engine index for maximum keyword exposure. More commonly used for database driven sites where multiple search queries can apply.

I think XML feed is just another name for RSS/Atom feeds.

There is also the OpenSearch format http://en.wikipedia.org/wiki/OpenSearch

And google sitemaps which give google a few hints on how to search and display results from your website

Thanks Rich. Those links were helpful.

Someone in another forum mentioned "intelligent automata" and I remembered
hearing about
Stephen Wolfram's cellular automata theory. The Wikipedia entry for this
contains suggestions that
this system may accurately describe natural processes throughout the universe.

A grand claim. Cellular automata are are useful approximation to
dynamical systems, which make them more tractable to work with.

This may then have some
bearing, though very remote, to permaculture relationships and guilds. Back
in the pcplantdb era
I thought a lot about heirarchies of relationships in a natural system on a
piece of land,
or 100 square feet, for that matter; the implications that the most basic,
elementary ecological relationships
in a system have for the whole system and for contiguous systems. The
language used by microorganisms,
invertebrates, insects, mammals and plants to communicate consisting of chemical, electrical, light, sound, pH, moisture and nutrient signals create complex relationships between the elements of any given natural system. This must play a large part in determining the biodiversity, robustness and overall health of any given site. Taking an inventory of
the components of such systems and all observable site features could be helpful to a permaculture designer when involved in site restoration as well as site development with increased diversity and production capability in mind.

Interesting thinking about hierarchies and nature. The way I see it is
that heirarchies are the work of man trying to impose some order on the
natural world. As we are humans we find them useful. But they are
limited, sets are a bit more flexable.

I think I'll post some of this to the PC list to see if there are any takers.

Curious whether a formal announcement of the pcdb wiki should be made to the
permaculture list (771 members now,
05/20/2007 - 105 more members than on 06/06/2006 when there were 666
subscribers).

A while yet. Ideally I'd like to see a bit more content there, so it
does not look so empty. I've still to implement the properties system
and improved search in full yet.


Just cam across an interesting piece:
A Group Is Its Own Worst Enemy
http://www.shirky.com/writings/group_enemy.html
lots on online communities, what makes them work etc.


BTW png uploads are now enabled.
