Welcome to OpenVocabularies.info
"We are happy to present Open Vocabulary, one of open source projects hosted by Knowledge Hives, that delivers Java API and REST API for managing knowledge organization systems. We use SKOS/RDF format to encode vocabularies that were not expressed before in RDF. The REST API enables browsing through the vocabulary space following publishing the Linked Data guidelines. You can start browsing from Vocabularies section." - Mike Chelen from Bookmarklet

Fwd: "Wikipedia for academic research". Post a summary of your research to increase its impact. http://acawiki.org/Home (via http://friendfeed.com/plosone...)
it looks like semantic mediawiki? - Mike Chelen
ah thanks, interesting to see which extensions they are using - Mike Chelen
Noteworthy: so far, 18 summaries of articles in PLoS Biol., 12 in PLoS Med. (None in PLoS ONE). - Jim Till
Perhaps noteworthy: the vast majority of edits in the last thirty days are by two people. It's hard to build critical mass... http://acawiki.org/index... - Andrew Su
the site looks pretty new, sometimes starting fresh produces the best results, although it can be useful to find some existing data to import initially - Mike Chelen
The site launched this week. The PLoS articles were seeded using the Editor Summaries that PLoS Bio and PLoS Med routinely publish - Peter Binfield
Peter: wondering if the data was converted from another format, or does PLoS supply RDF directly? is there any description of the process used? - Mike Chelen
We didnt work with them on this (other than to have some early meetings). I suspect they just copied and pasted... However, it can be extracted from our XML file of course. - Peter Binfield

"Timeline is a DHTML-based AJAXy widget for visualizing temporal information. This Drupal module is an integration for a JavaScript timeline widget developed by the SIMILE project. It works in a similar way as Google Maps but for time-based events. The SIMILE Timeline (and Ajax) libraries can be used from the SIMILE server or can be downloaded and installed into your (local) Drupal installation. This module provides a style plugin for the Views module that represents date information of nodes on a horizontal timeline display. It makes use of the Date module (if present) as source for temporal information defined on cck date fields of nodes." - Mike Chelen from Bookmarklet

"Views Datasource is a set of plugins for Drupal Views for rendering node content in a number of shareable, reusable formats based on XML, JSON and XHTML. These formats allow content in a Drupal site to be easily used as data sources for Semantic Web clients and web mash-ups. Views Datasource plugins output content from node lists created in the Drupal Views interface in a variety of formats - XML data documents using schemas like OPML and Atom, RDF data documents using a vocabulary like FOAF, JSON data documents in a format like Exhibit JSON, and XHTML data documents using a microformat like hCard." - Mike Chelen from Bookmarklet

USGS National Water Information System (NWIS) Water-Quality Web Services - http://qwwebservices.usgs.gov/
"USGS and EPA are working together to provide scientists and policy-makers an easier way to integrate access to their large water-quality databases. A common suite of web services allow for the automated sharing of water monitoring data via a common format and terminology. Initial web services are now available. A web service is a computer-to-computer protocol that allows for the direct sharing of information. The services will provide the ability to combine data from USGS's NWIS and EPA's STORET systems. The services will produce data formatted according to the Water Quality Exchange (WQX) Outbound XML schema, which has been developed collaboratively by EPA and USGS. Applications such as internet portals can use the web services to access data from both NWIS and the STORET Warehouse without needing an authorized database connection." - Mike Chelen from Bookmarklet
made a basic YQL open data table for this service, see http://friendfeed.com/watergo... for example - Mike Chelen

Trying to convert XSD's from http://qwwebservices.usgs.gov/schemas... to RDF for Drupal external vocabulary importer http://drupal.org/project/evoc wondering if XSD2OWL http://rhizomik.net/redefer... is the right tool?
Thanks for the reference. Interesting: a XSLT stylesheet handling a XSD document. I wonder if the complete XSD spec is supported. - Pierre Lindenbaum
how would it normally be done? found the site mentioned in the XML section on http://esw.w3.org/topic... - Mike Chelen
What do you mean with "normally' ? - Pierre Lindenbaum

"PPA for the Open Source Edition of the Virtuoso Universal Server from OpenLink Software. There is a lot of work yet to be done on this package, though it should already produce better results than building directly from upstream source. Once installed, browse to the pre-installed Conductor [1] application for the web administration interface." - Mike Chelen from Bookmarklet

I find myself agreeing with David Karger's position in http://groups.csail.mit.edu/haystac... The NIH reviewer's comments seem to suggest a doughnut hole -- predefined ontologies are too rigid but bottom-up ontologies are too risky to fund? Does anyone have any opposing thoughts?
I tend to agree although I take an even more radical position - which is that we need the tools that will help local ontologies be created as needed - and ideally these tools could be attempting the integration problem by seeking out similar data and descriptions elsewhere (which may be useful for the end user) and solving the "cut and paste" problem one step at a time, probably with... more... - Cameron Neylon
I can't comment on your funding question, but I definitely agree with everything Karger says in his post with regards to identifier resolution. Let the chips fall where they may, mint different identifiers for the same thing, write incompatible ontologies, mix your semantics, put it on the web in any format you like. As long as it is there, we will sort it out. - Greg Tyrelle

"Today's web is built predominantly for human consumption. Even as machine-readable data begins to appear on the web, it is typically distributed in a separate file, with a separate format, and very limited correspondence between the human and machine versions. As a result, web browsers can provide only minimal assistance to humans in parsing and processing web data: browsers only see presentation information. We introduce RDFa, which provides a set of XHTML attributes to augment visual data with machine-readable hints. We show how to express simple and more complex datasets using RDFa, and in particular how to turn the existing human-visible text and links into machine-readable data without repeating content." - Mike Chelen from Bookmarklet
