[10:00] GaryBergCross: Good architecture representation in slide 11 [10:07] MarshallXMa: @DouglasFils: Can you list a few example vocabularies used in your works. You mentioned vocabularies are important on slides 4 and 10 of your presentation. thx. [10:20] DouglasFils: @MarshallXMa: I am working to get our current vocabularies update into the web service.. some of the older versions are at http://data.oceandrilling.org/core/ We will try and use the w3c patterns for sharing the current vocabularies soon.. [10:21] DouglasFils: these are just simple SKOS files.. we would really like to leverage off NERC http://www.bodc.ac.uk/products/web_services/vocab/ [10:43] MarshallXMa: @DouglasFils: Thanks. [10:02] PeterYim: == DamianGessler presenting ... [10:13] anonymous1 morphed into DanCerys [10:21] PeterYim: @DamianGessler - does enabling a site to serve the data need to be done on the server side by the website provider, or will an enabled client be able to do it on any website? [10:22] PeterYim: if the former, do you have a list of your "partners"? [10:25] DamianGessler: @PeterYim - data providers host a SSWAP OWL RDF/XML graph for each service they offer. This "graph" describes their service semantically, allowing for discovery and (automated) engagement. [10:29] PeterYim: @DamianGessler - since your technology is quite domain independent, do you have plans to apply that to other domains beyond "plants" (if so, what domains are being worked on or considered? [10:32] DamianGessler: @PeterYim - geo would be natural (esp. because the of the scientific overlap between bio/geo/plant research). But no firm plans yet; open to follow-up. You are correct that the core technology is domain independent. [10:33] PeterYim: Thank you, Damian [10:22] anonymous2 morphed into PaulKoch [10:23] anonymous1 morphed into ToddPehle [10:23] PeterYim: == DaveKolas presenting ... [10:38] FranLightsom: Can anybody else hear? [10:39] PeterYim: @Fran - yes, I can still hear DaveKolas speaking [10:41] anonymous1 morphed into FrancescaQuattri [10:42] FranLightsom: Thanks. I needed to redial. [10:45] DaveKolas: Sorry, apparently my sickness resulted in me talking more slowly than usual. Please let me know if you have any questions about GeoSPARQL. [10:47] JohnGraybeal: @Dave: It was a very nicely put together summary of the technology, very neat to follow. What are the implications on the inference engine of having to satisfy geospatial relation queries? (How many support it, are they very much optimized (yet)?) [10:50] DaveKolas: The implementations that exist so far use geospatial indices to improve the processing of the queries, much like rdbms with geospatial extensions [10:50] DaveKolas: So query planning gets a little bit more complicated [10:51] DaveKolas: There are currently 3 implementations of which I am aware (Oracle, Parliament, and Strabon) [10:52] DaveKolas: Our hope is that other triple store vendors who currently have some proprietary spatial extensions (ex, Virtuoso) will eventually support GeoSPARQL [10:45] PeterYim: == VeronikaMegler presenting ... [10:53] anonymous1 morphed into AlexMirzaoff [11:07] PeterYim: == NaicongLi presenting ... [11:13] PeterYim: relay an anonymous post - URL to SDS Portal http://www.spatial.redlands.edu/sds/ [11:17] GaryBergCross: Break coming up after Naicong [11:17] PeterYim: @NaicongLi & PhilipMurphy - for the "collected" tools and models, are you working with those from your collaborators/partners or are they "discovered" from publications and the web? [12:37] NaicongLi: Peter -- I just saw your question earlier - "for the "collected" tools and models, are you working with your collaborators/partners or are they "discovered" from publications and the web?" The answer is "both". [11:21] GaryBergCross: Naicong's updated slides are on the Wiki (with "export" properly labeled now on slide#15). [11:24] PeterYim: @PhilipMurphy - possible typo on your email address on slide#28 [11:35] PhilipMurphy: Peter well spotted! -- should be philip_murphy@spatial.redlands.edu [11:36] PeterYim: @Philip ... you might want to send an update of the slides to Gary so he can swap it in for the archives [12:04] GaryBergCross: Updated slides for NaicongLi linked to the wiki session page now. [11:31] PeterYim: == [2:31pm EDT] NancyWiegand: we are having break now; resuming in 1 min. ... [11:35] PeterYim: == WenwenLi presenting ... [11:41] GaryBergCross: @WenwenLi - the attribute level looks like a values level. [11:52] anonymous2 morphed into Alex [11:54] PeterYim: == ToddPehle presenting ... [12:10] GaryBergCross: @Todd - Is subset the right way to partition some space? [12:21] ToddPehle: Hi Gary, VoID subsets are generic ways to partition a dataset (not so much a space); One obvious use for this is finding the download URL of an RDF file by "Country" (say in Geonames dataset) [12:22] ToddPehle: You could also specify these feature types have data in that particular "Country" [12:15] GaryBergCross: @Dave @Todd You 2 need to have a Hackathon on these ideas.. [12:17] DaveKolas: @Todd... can you repeat the question you asked about representing CRS's in RDF? [12:24] ToddPehle: Dave, I wanted to use geosparql:asWKT to describe BBOX; as I understand it, CRS is specified inside the geometry literal...is this correct? I was hoping I could directly assert CRS in RDF with geosparql vocab. [12:25] DaveKolas: The CRS only lives in the literal in GeoSPARQL, but you could potentially reference its uri with a different property... I'm not sure what you mean about using asWKT to describe BBOX? Do you mean an instance of a bounding box, or the concept of bounding boxes? [12:29] ToddPehle: @Dave Ok. Will check out the CRS URI...I was referencing an instance of a bounding box (encoded as wkt). [12:31] DaveKolas: So wouldn't a bounding box representation require a crs, and go in there in the normal way? [12:32] DaveKolas: Why do you want it *not* in the literal? [12:32] ToddPehle: Sorry, should have explained better. I was looking for a way to ask "What feature types are in dataset ABC that use EPSG:4326?". [12:32] DaveKolas: Ah! [12:32] ToddPehle: ...without having to scan every WKT literal to detect. [12:33] DaveKolas: Got it. If there isn't one already, there should be a filter function for getting the crs out of a literal [12:33] DaveKolas: and that could be optimized on the kb side [12:34] ToddPehle: Great. Thanks! [12:24] PeterYim: == ChaoweiYang (Phil) presenting ... [12:25] GaryBergCross: Should slides be advancing? [12:29] PeterYim: @Phil - ref. your slide#7 ... are your planning to stand up your own ontology repository; if not, what/who are the ontology repository people you are planning to work with? [12:43] PeterYim: @Chaowei - please look at what we are doing in the OOR Initiative - see: http://oor.net ... and in particular the SOCoP instance at: http://socop.oor.net [12:39] GaryBergCross: @Chaowei This use of social science methods for developing ontologies/ODPs is a good topic for a future SOCoP workshop. [12:40] PeterYim: == NancyWiegand: open Q&A ... [12:36] GaryBergCross: BTW Follow on questions and discussion is possible later using the SOCoP Forum http://ontolog.cim3.net/forum/socop-forum/ [12:38] GaryBergCross: Any thoughts out there on the value and interest in a workshop on this in the Fall? Who would be interested in coming? [12:43] JimJacobs: Many thanks to all the speakers and organizers. Cheers! [12:47] GaryBergCross: @Jim - One step in that direction is the deepening modeling of Roles which are social in nature... NicolaGuarino is one source of these ideas..
