Abstract The OWL 2 Web Ontology Language, informally OWL 2, is an ontology language for the Semantic Web with formally defined meaning. OWL 2 ontologies provide classes, properties, individuals, and data values and are stored as Semantic Web documents. OWL 2 ontologies can be used along with information written in RDF, and OWL 2 ontologies themselves are primarily exchanged as RDF documents. The OWL 2 Document Overview describes the overall state of OWL 2, and should be read before other OWL 2 documents.

We're IT! Current b/ITe (v31n5) » b/ITe Archives Virtual Events What’s New Categorized | Uncategorized Metadata for Video: Too Much Content, Not Enough Information Posted on 31 August 2012. by Wayne Pender, McGill University, 2012 Joe Ann Clifton Student Award Winner (Published September 1, 2012) Abstract Television news libraries have struggled with cataloguing, organizing and storing visual materials for efficient search and retrieval for years. This task has been complicated by the emergence of digital video and the exponential growth in the holdings of television news libraries. In parallel, the ability for non-professionals to shoot, edit and publish videos of increasing production value and complexity on the web has flooded the Internet with videos that appeal to a wide audience and subject interest. The present survey looks at the metadata protocols and practices in place for an internal audience in professional operations and on display for the general public on the Internet. The study finds that the lack of a common metadata schema can make much of the material inaccessible. Literature pertaining to this area is reviewed and future direction is discussed. http://it.sla1.org/2012/08/metadata/ 1/10 3/1/2019 Metadata for Video: Too Much Content, Not Enough Information | SLA Information Technology Division Keywords: metadata, video, XML, RDF, MXF, television, news, YouTube Paper Searching and retrieving visual content is problematic. The search for specific moving images on film and video has long been a task for television news professionals, but now with wide spread availability of video resources on the Internet it has become a task for anyone.

  • Instruction for Using XML Notepad
    Using XML Notepad to Read, Edit, and Parse FGDC-CSDGM XML Metadata. Currently many tools exist that allow a user to work with XML metadata files. However, most of the main metadata creation/editing tools do not provide a means of validating a metadata record for compliance with the FGDC-CSDGM standard or its variants, such as the Biological Data Profile (BDP) standard. One of the most reliable ways to validate metadata files (that is, check files for completion and/or errors) is with the USGS Metadata Parser (MP) utilities. The MP tool and the other tools distributed in the package were developed by Peter Schweitzer and are freely available online (http://geology.usgs.gov/tools/metadata/tools/doc/mp.html). Once configured properly, MP can process metadata files and be used to produce a text file with a list of all errors found. A user can then use this list of errors to find and correct the problems using a text editor or the metadata editor of their choice. The challenge with this method is that finding and correcting the error within a metadata editor based solely on the error message from MP can be confusing and frustrating. Additionally, if there are many errors or complex problems to correct, the process will require multiple iterations of running MP and subsequently correcting errors in a metadata editor. All in all, the process can be fairly time consuming and onerous, especially for those without a detailed understanding of the FGDC-CSDGM standard. The methodology for metadata editing and validation described in this document tries to address some of these problems with an alternative approach.

  • Cisco XML Schemas
    CHAPTER 14 Cisco XML Schemas This chapter contains information about common XML schemas. The structure and allowable content of the XML request and response instances supported by the Cisco IOS XR XML application programming interface (API) are documented by means of XML schemas (.xsd files). The XML schemas are documented using the standard World Wide Web Consortium (W3C) XML schema language, which provides a much more powerful and flexible mechanism for describing schemas than can be achieved using Document Type Definitions (DTDs). The set of XML schemas consists of a small set of common high-level schemas and a larger number of component-specific schemas as described in this chapter. For more information on the W3C XML Schema standard, see this URL: http://www.w3.org/XML/Schema This chapter contains these sections: • XML Schema Retrieval, page 14-135 • Common XML Schemas, page 14-136 • Component XML Schemas, page 14-136 XML Schema Retrieval The XML schemas that belong to the features in a particular package are obtained as a .tar file from cisco.com. To retrieve the XML schemas, you must: 1. Click this URL to display the Downloads page: http://tools.cisco.com/support/downloads/go/Redirect.x?mdfid=268437899 Note Select Downloads. Only customer or partner viewers can access the Download Software page. Guest users will get an error. 2. Select Cisco IOS XR Software. 3. Select IOS XR XML Schemas. 4. Select the XML schema for your platform. Once untarred, all the XML schema files appear as a flat directory of .xsd files and can be opened with any XML schema viewing application, such as XMLSpy.

  • The Development of Algorithms for On-Demand Map Editing for Internet and Mobile Users with Gml and Svg
    THE DEVELOPMENT OF ALGORITHMS FOR ON-DEMAND MAP EDITING FOR INTERNET AND MOBILE USERS WITH GML AND SVG Miss. Ida K.L CHEUNG a, , Mr. Geoffrey Y.K. SHEA b a Department of Land Surveying & Geo-Informatics, The Hong Kong Polytechnic University, Hung Hom, Kowloon, Hong Kong, email: [email protected] b Department of Land Surveying & Geo-Informatics, The Hong Kong Polytechnic University, Hung Hom, Kowloon, Hong Kong, email: [email protected] Commission VI, PS WG IV/2 KEY WORDS: Spatial Information Sciences, GIS, Research, Internet, Interoperability ABSTRACT: The widespread availability of the World Wide Web has led to a rapid increase in the amount of data accessing, sharing and disseminating that gives the opportunities for delivering maps over the Internet as well as small mobile devices. In GIS industry, many vendors or companies have produced their own web map products which have their own version, data model and proprietary data formats without standardization. Such problem has long been an issue. Therefore, Geographic Markup Language (GML) was designed to provide solutions. GML is an XML grammar written in XML Schema for the modelling, transport, and storage of geographic information including both spatial and non-spatial properties of geographic features. GML is developed by Open GIS Consortium in order to promote spatial data interoperability and open standard. Since GML is still a newly developed standard, this promising research field provides a standardized method to integrate web-based mapping information in terms of data modelling, spatial data representation mechanism and graphic presentation. As GML is not for data display, SVG is an ideal vector graphic for displaying geographic data.

  • Determining the Output Schema of an XSLT Stylesheet
    Determining the Output Schema of an XSLT Stylesheet Sven Groppe and Jinghua Groppe University of Innsbruck, Technikerstrasse 21a, A-6020 Innsbruck, Austria {Sven.Groppe, Jinghua Groppe}@uibk.ac.at Abstract. The XSLT language is used to describe transformations of XML documents into other formats. The transformed XML documents conform to output schemas of the used XSLT stylesheet. Output schemas of XSLT stylesheets can be used for a static analysis of the used XSLT stylesheet, to automatically detect the XSLT stylesheet, which has been used for the trans- formation, of target XML documents or to reason on the output schema without access to the target XML documents. In this paper, we describe how to auto- matically determine such an output schema of a given XSLT stylesheet, where we only consider XML to XML transformations. The input of our proposed output schema generator is the XSLT stylesheet and the schema of the input XML documents. The experimental evaluation shows that our prototype can de- termine the output schemas of nearly all typical XSLT stylesheets. 1 Introduction Among other usages of XML, XML is the most widely used data model for exchang- ing data on the web and elsewhere. For the exchange of data, we have to transform the data from one format into another format whenever the two exchange partners use different formats. The exchange partners can use different formats, which might be a proprietary company standard, a proprietary application format or other standard for- mats, for historical, political or other reasons. We focus on XSLT [23] as transforma- tion language for the XML data.
