I just discovered an interesting project called "Add Your Own":
http://www.addyourown.com/
It's a wiki restaurant review system! They even have a rudimentary metadata
system for locations and restaurant types. Is it worth us plugging the OG
system to them?
One interesting thing their site does that ours doesn't is a summary view:
http://www.addyourown.com/neighborhood.php?nbh_id=13
I think this is a smart innovation. It would be nice to be able to do that
for a given category - see a list of all the nodes, with selected metadata
fields, in a tabular format. Maybe this is something I should have a go at,
since it's long overdue that I contributed some more code.
Ha! Someone's already mentioned us to them! Fantastic.

I'd be interested in setting up an open guide to Sheffield, or at least trying
to. Think I can find a few people who would contribute from the start. What
would I need to do?

>From "Changes":
Numerous template tweaks to comply with the W3C's Web Content
Accessibility Guidelines (http://www.w3.org/TR/WAI-WEBCONTENT/):
- summaries for all HTML tables
- labels for all form input elements and some textual additions
to templates, such as '/' separators between navbar items,
because the guidelines specify links should not only be
separated by whitespace. If you don't want these to appear,
put the following in your stylesheet and they'll be hidden by
CSS (but will still appear for people using textual browsers or
screen readers): ".hidden { display: none }".
- the "lang" element (a two-letter code identifying the language
you're writing pages in) will now be added to the <html> tag on
all pages; a new question has been added to the configuration
script to ask for it and it will be stored in wiki.conf.
*** YOU WILL NEED TO RUN BUILD.PL AGAIN. ***
*** Remember to keep a backup copy of your old wiki.conf! ***
Improved navigation for search results (next and previous n hits).
Removed underscores from page names in search results.
Please test if you can.

I've CC'ed this to the OpenGuides developers' list so people can comment.

Yes, that's right. Some of them live on the same machine, but most don't.

At the moment, no. It would be a nice feature, I think, to have something
like the InterMap (http://www.usemod.com/cgi-bin/mb.pl?InterMap) idea so you
could say "blah blah the [Paris:Arc De Triomphe]", or something like that,
probably located on openguides.org that could be polled for updates.

The minimum is actually zero - there are no mandated fields, because not
every node is actually geospatial in topic.

At the moment, that's done by making calculations based on Ordnance Survey
coordinates that have been entered for the nodes, because that system
defines a convenient grid that's easier to manipulate for those calculations
than lat/lon figures - none of this tricky business with oblate spheroids.
We're very aware that this is proprietary to the UK, though, and are looking
into ways to replace it. In the last day or two, someone brought the UTM
system to my attention, and it seems to be a very good candidate
(http://search.cpan.org/~grahamc/Geo-Coordinates-UTM-0.03/UTM.pm).

Not yet, no, partially because of the insane cost of map data for this
country
(for example:
http://www.ordnancesurvey.co.uk/oswebsite/products/10kraster/pricing.html).
We'd be very interested in having a map interface. Ivor Williams (who'll
read this on the list) is looking into doing visualisations of the stuff in
an OpenGuides database.

Well, we've been around a couple of years but people have only started
contacting us and making their own sites around the world for the last few
months. There's a newborn OG install for San Francisco as of the other week
(http://sf.openguides.org/). Similar projects I know of are Wikitravel
(http://www.wikitravel.org/) and World66 (http://www.world66.com/), but
they're not particularly North American. There's also a New York restaurant
guide thing that's fairly similar in idea, but I'm damned if I can find it
right now.
Best,
Earle.

Sounds like I need to pull my finger out and write the Geography::Grid
module I have been meaning to write. I think I've got the tuits to do this in
non-work time at the moment. I should also write this up as a hack once
I've done it.
Ivor.
hi again,
as briefly mentioned on irc we'd like to set up an open guide to san
francisco. i wonder what the oslo people did to de-UK-ify their openguides
- just delete the OSX and Y fields from their template?
the openguides we ran at etcon not really for geographic purposes i
did fix up to accept UTM and convert back and forth between lat and long
(and OS numbering is just a UTM coordinate with a digit missing i learned)
also i was thinking of plugging in a geocoder to generate lat and long
from street addresses - e.g. http://headmap.org/geocoder/geolookup.cgi -
postcode boundaries being very large here.
is anyone else looking at that, i could try and assemble these changes
into a patch but they were a bit messy and should be config options...

hi openguides,
(hi ivor, i saw moblogged pictures of you talking about mapping openguides
to the SVG people at http://moblog.nicecupoftea.org the other day. hope
you enjoyed it... )
you might not know schuyler and rich are working on a 'mapping hacks' book
from ORA and soliciting user contributions from the wild. there are three
openguides hacks pencilled in to it, all of which have my name on them.
i thought a/ ivor might like to write up his talk into a hack, the book
doesnt have enough SVG in it, b/ kake might like to write a hack based on
some of that perl.com article, including new features c/ i'm not really
trying to palm it off onto other people, but reckon you would do it better
than me if i could persuade you.
a 'hack' is typically 1000-2000 words in length, and includes about 50
lines of interesting code, and is focused on getting a simple thing done.
the list is at http://mappinghacks.com/cgi-bin/hacks.cgi

Last night I gave a talk at the London SVG Users Group on drawing maps for
OpenGuides.
http://un.earth.li/~ivorw/slides/ogmaps.ppt
I have had feedback that it was well received, and I am contemplating giving a
variant of the talk to London.pm. Hopefully I will be able to get some working
demos ready for the talk :).
Ivor.
