[OpenGuides-Dev] simple OGL map service
by Jo Walsh 23 May '05

23 May '05

hello list, because i was aggregating the information anyway, i made a simple openguides map service for the London guide, i thought people might be interested in this, e.g.: http://map.wirelesslondon.info/map/openguides?zoom=3 There's no styling to speak of, & this service just plots all the geo:SpatialThings it knows about within the bounding box shown on the map. There is a simple CGI-drivable interface that lets you do a bit more, http://map.wirelesslondon.info/dev/map/ illustrates that. The hope is to start aggregating street data from (and contributing to) http://openstreetmap.org/ , that will enhance the base map layer... also to do a UK-wide one useful for consume.net usign a WMS, web map service for the data - again the grainy satellite pictures, but useful for something? and i will start tyring to aggregate spatial stuff from other OGs as well ;) Anyway, i'd like to work this map service into something useful for OG - the idea with the above URL is it can be displayed in an iframe a-la google maps. What kind of things would you want to plot at once? As now, you can just generate text files and post the URLs of them, i would also like to be able to do this with RSS feeds, that will be implemented soon if people want it... -jo

[OpenGuides-Dev] database dump
by Daniel Smith 19 May '05

Are database dumps available? I currently spider for the RDF, but for the sake of your resources would prefer a more direct way to access it. Even a list of all RDF pages would be better. Daniel Smith

[OpenGuides-Dev] Re: evnt-discuss: augmenting RSS with FOAF...
by Jo Walsh 17 May '05

17 May '05

hi re, sorry dropped thread, this is a longish one, more openguides stuff below... > share it among 3 people. i think we're going to get a lot of that. does that > make any difference? nnng; perhaps, in a worst case; if i start reasoning about things based on those properties which i acquire from you; if i had other information about more than one of those people, if more than one of them became associated with that address, i might accidentally collapse them into a multi-limbed, polypresent uber-person. This, however, is largely my problem. So if i start using a squishing algorithm to create identities from FOAF data while you're publishing unique identifiers for non-unique things; which are identifiers that i'm likely to hear repeated from other sources... well, i can be more cautious about what i accept from the world and start making new conclusions with. And you can be cautious about what you emit... but do you want people to have to set a 'this is a group account' flag and not emit email addresses? Perhaps it's just okay to not worry about it. > > right, i didn't realise the RDF/xcal representation was going to be > > somewhere else as well. if the changes.rss could offer rdfs:seeAlso > > links to fuller RDF representations that would be ideal. > okay. i'm not too clear on syntax around this kind of thing. given that we want > to retain some kind of pubDate, and have seeAlsos, etc, what would an <item> > look like now? well, i don't know what predicate/property to recommend using to indicate pubDate as a concept in RSS1 that doesn't affect the semantics of what you're talking about. perhaps just having a pubDate / ical:datetime / whatever on the item, and differentiating between the item (the uri of the page about the object (the event)) and the object actually under discussion. Have a look at: http://london.openguides.org/api/rdf/category/Bookshops That features an RSS feed with seeAlso links which are to the RDF version of each URI. If you look at http://london.openguides.org/index.cgi?id=Freedom_Bookshop;format=rdf You see it differentiates between properties of that URI, the page containing information about the thing, and the relative URI #obj which is the URI which refers to the actual thing in itself. Does this make sense? It is a nuanced issue the background of which you can dig at with a search for "HTTP-Range-14". It may sound a little obtuse but i found it later helpful when modelling metadata properties of things (people, spaces), rather than descriptions of or references to things (wiki pages, web service URIs) Re. the broader hookup between OGL, EVNT and wirelesslondon: - We'd get a feed from EVNT anyway, of stuff we'd been able to reason was nearby. for WirelessLondon, we'd probably want to consume everything you thought was in London, up front. We'd want to share this with the Open Guide to London; and OGL will offer a kind of fuzzy node-coder service, so you can send an address string, see if OGL has anything that matches your place/venue, and attach your evnt to it; this should be one-click for the user; then easy to POST new pages, which perhaps can be wiki-gnomed and made into redirects later, if auto-generated page node titles aren't to the Guide admins' tastes. - Someone logs into Wireless London via the portal service. They could do this via the web as well; we don't *force* them to authenticate to the portal, they can pass straight through if they like. Each node knows where it is, and shows a listing of local resources from the Open Guide; ideally, EVNTs that we've managed to geocode within 1000m. Once the user logs in, we have their personal information that they gave us when they registered; it is just part of a big old triple store into which we are also aggregating RSS, geo, FOAF data. If we have mbox_sha1sum annotations from you, we say, "here's an event you've annotated, therefore this is probably your evnt account, log in here". If we can really get people using this service - i've toyed with the idea of *obliging* the Season of Media Arts for London organisers to use the portal service, they don't get access to their tools via the web - this means they have to go socialise in a cafe with open wireless, or set up a Wireless London portal node at home ;) - well, we get a lot of for-free association. We know where the user is in space, and in time, and we know *who* they are, what information resources they are connected to. And we are starting to know a lot more about the things around them, in space and time and more abstract network sociality; from EVNT and from the Guide particularly. Because it is being accessed with a knowledge of these properties, the system starts to refract connections in the information near them. I'm connecting to the network; I'm in a cafe in South Kensington; my calendar says i'm supposed to be at a meeting at the Data Centre in an hour's time. Saul will be there, and i have a postponed mail waiting to go to him two days now, and... I should stop there, but perhaps others have more of that picture. Almost without architecture, just through the edges, we can almost do amazing things. -jo

[OpenGuides-Dev] Fuzzy matching node names
by Earle Martin 16 May '05

16 May '05

I've been in discussions with some people about the possibility of linking other services to OpenGuides. One thing that occurred to me would be the utility of providing a fuzzy node name lookup. Here's a user story: Users of website X want to be able to associate nodes on OpenGuides site G with items on X. They go to a node lookup service offered by G and type the name of something they are looking for. They are then presented with a list of nodes on G that approximately match their search term. Specifically, I'm thinking of search results gradiated into exact matches, partial matches and approximate matches, just like the way IMDB does it: http://uk.imdb.com/find?q=Hideous I don't know anything about fuzzy matching techniques. Can anyone suggest any pointers? -- Earle Martin http://downlode.org/ http://purl.oclc.org/net/earlemartin/

[OpenGuides-Dev] YAPC::Europe 2005
by IvorW 14 May '05

14 May '05

I don't know who is intending to go. The dates are 31st Aug to 2nd Sep. I intend to go myself, and I have submitted one talk proposal already. Since the theme this year is "Perl Everywhere", it would be a nice place for a talk on OpenGuides. I'm offering to submit a talk proposal. The talk will include some of the material from my Geographical Modules talk, but also some new sections: - Wiki spam and how to deal with it - UTF-8 and language problems - Copyright and creative commons Please give me feedback before I submit the proposal tomorrow (which is the submission deadline) Ivor.

[OpenGuides-Dev] CVS repository
by Dominic Hargreaves 12 May '05

12 May '05

Hi, The CVS repository on un has been inaccessible for quite some time now. I would like to suggest that we move it elsewhere: I would be willing to host it on a colo machine I run providing pserver access. This would additionally allow anonymous access which hasn't been the case so far. Thoughts? -- Dominic Hargreaves | http://www.larted.org.uk/~dom/ PGP key 5178E2A5 from the.earth.li (keyserver,web,email)

We stock some of the best known fashion labels and have been going for 16 years. We would like to be featured on your site in either a shopping section or an events listing, or both. Please let us know how to go about implementing this. Our website is www.designersales.co.uk. Thank you very much. Best Regards Sophie Shephard Designer Sales UK

[OpenGuides-Dev] mooted hackfest
by Jo Walsh 21 Apr '05

21 Apr '05

hello, the list would be welcome to use the map room at limehouse town hall for a hackfest. it could accomodate up to 12 easily and has all requisite network, spare computers etc. i found an old hackfest-organising page on the wiki and edited it. http://openguides.org/dev/?node=Hackfest There are a few things i'm especially interested in at the moment: * Authentication / Authorisation * Integration with the [http://uo.space.frot.org/?LondonFreeMap London Free Map] services as they expand. * Connection to event listings from [http://b.evnt.org/ EVNT], [http://upcoming.org/ upcoming] and similar. the open geodata project side of things will hopefully start coming together properly over the next couple of weeks. perhaps list members might be interested in the upcoming "Forum on Open Geodata" at the Stanhope Centre next Thursday, April 14th: http://www.okfn.org/wiki/OpenKnowledgeForums There will be a collection of people working on free mapping and geodata collection projects, and also a gang of policy oriented types who have had their GIS work shackled by government infolicensing practises, and some people doing 'civil society' work... -jo
