New tools: Sindice Inspector, Full Cache API – all with Online Data Reasoning
Full announcement at http://blog.sindice.com/2009/10/12/new-inspector-full-cache-api-all-with-online-data-reasoning/ quotable text: --- We’re happy to release today 2 distinct yet interplaying features in Sindice: The Sindice Inspector and the Sindice Cache API (both including Sindice’s Online Data Reasoning). A) Sindice Inspector - Takes anything with structured data on (RDF, RDFa, Microformats), and provides several handy ways: * in a “Sigma” based view * a novel card/frame based view * a SVG based interactive graph view (a la google map) * sortable triples, with prettyprint namespace support * full ontology tree view for Online Data Reasoning debugging - Does live Online Data Reasoning: allows a data publisher to see which ontologies are implicitly or explicitly (directly or indirectly, via other ontologies) and * visualizes the full closure of inferred statements using different colors. * provides a tree of the ontologies in use and their dependencies. Ways to use it: * a tool from Sindice.com (the inspect tab on the homepage) or the Inspector Homepage * a Bookmarklet (drag it to your bookmark bar and use while browsing) * an API either raw (Any23 output, no reasoning) or with reasoning * to send links to structured data files around, every visualization has its own permalink. Examples: * Sortable Triples with Reasoning Closure (try) http://sindice.com/developers/inspector/?url=http://dbpedia.org/resource/Lough_Corrib&doReasoning=true#triples * Ontology Import Tree of Axel Polleres’s DERI foaf file (try notice how the GEO ontology and the DCTerms elements are only imported indirectly via other ontologies but yet contribute to the reasoning) http://sindice.com/developers/inspector?doReasoning=true&url=http%3A%2F%2Fwww.deri.ie%2Ffileadmin%2Fscripts%2Ffoaf.php%3Fid%3D58#ontologies * Graph of the RDF representation of Axel’s Facebook public profile (from microformats) http://sindice.com/developers/inspector/?url=http%3A%2F%2Fwww.facebook.com%2FAxelPolleres%3F_fb_noscript%3D1#graph * All the data in a eventful.com page http://sindice.com/developers/inspector/?url=http%3A%2F%2Feventful.com%2Fwinnipeg%2Fevents%2Fmetallica-%2FE0-001-025118008-2#fullcontent B) Sindice Cache API Tired of your favorite data being offline now and then? convinced that you can’t really do a linked data application without any network safety net? rejoice :-) . With the Sindice Cache API you can: * access and retrieve any of the currently 64 million RDF sources in Sindice with a simple REST api; * access and retrieve the full set of inferred triples created by Online Data Reasoning (instant access to the precomputed closure, 0 wait time); * visualize the cache with the same handy tools as available in the inspector. Just try from any Sindice result page. Feel free to use Sindice Cache with reasoning as a fallback service when data is not available and as a way to add full recursive ontology importing + reasoning support to your application (with none of the massive pain associated with the full procedure). A document you need is not in the cache? just ping the URL in and it will be available within minutes; ———- But what is Online Data Reasoning exactly? Background and implementation When RDF/RDFa data is put out there on the web, the “explicit” information given in the data is just part of the story. Reasoning is a process by which the vocabulary used in the data (Ontologies) are analyzed to extract new pieces of information (otherwise implicit) – e.g. giving a “date of birth” to an “agent” would makes that a “person”. Typically, Semantic Web software have manually imported the ontologies they needed. If ontologies are published using W3C best practices, however, it becomes possible to do the entire process automatically: ontological properties can be resolved (i.e. as they are resolvable URIs, they are HTTP fetched) and therefore all can be imported automatically … … but ontologies can import other ontologies, and form circles and so on.

Re: ANN: alternative to cURL for debugging URIs
In message <200910121602.23834.har...@informatik.hu-berlin.de>, Olaf Hartig writes Dear LODers, We announce a new tool for Linked Data publishers as well as developers of Linked Data based applications. You may use our tool [1] as an alternative to the command line tool cURL for debugging Linked Data sites [2]. Our tool allows you to dereference URIs and it visualizes the HTTP response of the server. In contrast to cURL, you may directly select each URI that occurs in the response in order to initiate the dereferencing of the selected URI with our tool. Hence, with our tool you may avoid the cumbersome copying and pasting of URIs on the command line as is necessary with curl. Furthermore, you may view the response body in different RDF serialization formats and you may inspect RDF data embedded in XHTML+RDFa documents. To make our tool a real Linked Data application that can also be accessed by software agents we embed an RDF description of the visualized HTTP messages in the HTML output. Very nice. The only glitch I found was when URLs contain the ampersand character, e.g.: http://collections.wordsworth.org.uk/object/GRMDC.C104.2 when resolved as HTML yields a 301 Moved Permanently, whose URL should include the trailing "&objectname=GRMDC.C104.2" (but doesn't).
