blogosphere collaborative location annotation - RestaurantRecommendation RDF is just a graph the nodes in the graph are URIs and strings the labels are URIs for published vocabularies (like FOAF or Dublin Core) a unique URI to identify a space a simple vocabulary for talking about spaces and the connections between them a RESTful web interface to query, and add to, the RDF model a consensus ontology, expressed in OWL, to allow reasoning about the model mudlondon is an RDF model of london 'mudlondon' is also a bot that talks jabber, AIM and IRC. the model can be explored like a MUD, and commented, annotated and augmented through the bot interface the bot uses the RESTful web interface as a 'brain' the URIs can be derefenced by any bot or spider to see metadata about that place wandering round the City of London a sample of the RDF at a spacenamespace URI <space:Space rdf:about="/London/Swiss_Re_Building#space"> <space:type>Building</space:type> <space:name>Swiss Re Building</space:name> <dc:creator>metazool@localhost</dc:creator> <space:postcode>EC3A 8EQ</space:postcode> <space:os_x>533270</space:os_x> <space:os_y>181204</space:os_y> <geo:long>-0.080814</geo:long> <geo:lat>51.514050</geo:lat> <space:connects> <rdf:Description rdf:about="/London/St._Mary_Axe#space"> <space:name>St. Mary Axe</space:name> <rdfs:seeAlso rdf:resource="/London/St._Mary_Axe#space"/> <space:type>Road</space:type> </rdf:Description> </space:connects> </space:Space> REST - REpresentational State Transfer GET/POST requests over HTTP query and update the model none of the complexity of WSDL, XML Schema or SOAP using the semantics of the URI space as Tim intended annotating places, and connecting them like new rooms in a MUD the bot allows for tagging locations with geodata, and commenting on them, using the FOAF vocabulary for people annotating them with pictures and urls creating new spaces and connecting them together. locations have pointers to other sites on the web the bot can GET and POST to different functions to query and update the model, and see the results in RDF <space:comment> <rdf:Description rdf:about='/london/Porterhouse_Covent_Garden#space'> <foaf:nick>metazool</foaf:nick> <dc:date>2003-03-12</dc:date> <dc:text>nice house beers, but this huuuge place tends to be crowded with braying suits</dc:text> </rdf:Description> </space:comment> <space:near> <rdf:Description rdf:about="/london/Chandos#space"> <space:name>Chandos</space:name> <space:distance>0.43 miles</space:distance> <rdfs:seeAlso rdf:resource="/london/Chandos#space"/> </rdf:Description> </space:near> http://grault.net/grubstreet/ - 'the open source guide to london' embedding RDF geocoded data in each page augmented RSS1.0 feed of new pages http://knowhere.co.uk/ - the users' guide to the UK http://forums.upmystreet.com/ - location-based 'conversations' the RDF is designed to allow open data sites to share and aggregate their mapping information everyone can see a little bit of the picture http://www.landmap.co.uk/tools.html offering an RDF/XML interface to wireless plotting tools latitude, longitude and altitude of nodes and terrain between them http://consume.net - the UK nodedb - Ordnance Survey grid references consume has an augmented RSS1.0 feed of new nodes when mudlondon is told about new types of space, it submits them to an 'ontobot' over jabber the ontobot uses the same RDF/REST infrastructure to maintain an 'ontological' model OWL, the w3 Web Ontology Language, allows for taxonomic descriptions, properties and logical constraints in the spatial model encapsulating psychological factors in logical inference, such as 'psychological distance' over a route. the Scalable Vector Graphics format is popular in the formal GIS world. it can convert between different co-ordinate systems simply and animate a collaborative map as it builds up or routes as they are traversed or a historical map as it changes RDF's graph model is ideal for routefinding traversal OWL rules allow us to encapsulate psychological factors in logical inference flipping the RDF model back and forth in time both visually, and in the graph the temporal and spatial dimensions are intertwingled old maps of hackney http://www.pepysdiary.com/ is re-running pepys' diary in blog format for the next ten years... with collaborative annotations, and references to locations we can build representation of spaces moving through time everyone can see a little bit of the picture we build up the bigger picture from individual, interconnected models overlaid on traditional maps, we may see things we hadn't noticed before this fits well with the general philsophy of the semantic web. in the UK, collaborative mapping is driven by necessity all mapping and location data is 'Crown copyright' in the hands of commercialised government offerings free online mapping services like Streetmap and Multimap have had to remove functionality for fear of copyright violations even the outline shape of Britain is copyrighted. local government wastes millions duplicating GIS software and development effort. this doesn't have to be a dichotomy data from open community review sites like knowhere.co.uk and grault.net/grubstreet/ the tube model was scraped from free locator services like tubeplanner.com political attitudes to public geodata in different countries UK and britain are closed, US and denmark are open collaborative cartography is a potential exit route from hegemony. 'presence' in jabber, space:location for foaf:Persons landmap provides a locator service for open wireless nodes consume.net provides feeds of new nodes, and the potential for a full RDF/XML interface triangulation and topography between nodes hoping to learn more from http://maps.nocat.net/ especially to: blech and craneporn.org ephidrina and foafnaut.org mattb and picdiary.com earle and grault.net/grubstreet rocco and poe.perl.org dmiles and logicmoo.sf.net
