ISO DSDL Overview Standing for "Document Schema Definition Languages", DSDL is a recognition that the validation of XML documents is a subject too wide and complex to be covered by a single language. DSDL can be seen as a framework and set of languages to check the quality of XML documents and this issue appears to be crucial for any XML based application. DSDL Part 9 is for these people who would like to rely on years of usage of DTDs without loosing all of the goodies of newer schema languages. www.idealliance.org /papers/dx_xml03/papers/04-03-03/04-03-03.html   (2049 words)

ICRA rating rationale - The Delhi Safe Deposit Company Limited   (Site not responding. Last check: 2007-10-09) DSDL’s collection efficiency [Collections/(Billings+Opening Debtors)] in lease declined from 93.4% in 1996-97 to 91.3% in 1997-98 (due to a few delinquent accounts) while in hire purchase it increased from 96.5% in 1996-97 to 99.6% in 1997-98 (following collection of entire overdues of the previous year). DSDL recognises penal interest on delayed lease and hire purchase instalment receipts on an accrual basis, which has resulted in overstatement of income in 1997-98. DSDL is likely to report higher profits in 1998-99 due to increase in lease and hire purchase income. www.debtonnet.com /icrarr/fssep98ds.htm   (1401 words)

XML.com: DSDL Examined While researching this week's article, I was surprised to note that while DSDL has been referred to for some time in several forums, including XML-DEV and this column, there isn't much published information about the project, which is actually in a very embryonic stage. DSDL, as its home page notes, aims to "create a framework within which multiple validation tasks of different types can be applied to an XML document in order to achieve more complete validation results than just the application of a single technology". DSDL will provide a framework for mixing together multiple schema languages, which allows the user to avoid choosing a single language and to benefit from the strengths of several languages. www.xml.com /pub/a/2002/06/26/dsdl.html   (1211 words)

XML.com: DSDL Interoperability Framework DSDL ("Document Schema Definition Languages") is a project of the ISO/IEC JTC 1/SC 34 (chair, Jim Mason) Working Group 1 (chair, Charles Goldfarb). DSDL is necessary because other XML schema languages (primarily W3C XML Schema) do not meet the needs of "document heads", and document validation is too complex to be done using a single language. The chief design principle of DSDL is to split the issue of describing and validating documents into simpler issues: grammar based validation, rule based validation, content selection, datatypes, and so on. www.xml.com /pub/a/2003/04/30/dsdl.html   (1109 words)

Appendix A. DSDL DSDL (Document Schema Definition Languages) recognizes that the validation of XML documents is a subject too wide and complex to be covered by a single language. The goal of DSDL is to provide a means to fill out these gaps and to cover the whole domain of document validation. DSDL can be seen as a framework and set of languages that checks the quality of XML documents, a crucial issue for any XML based application. books.xmlschemata.org /relaxng/relax-APP-A.html   (368 words)

[office] Clarification re: DSDL and W3C Schema I was the first project chairman of DSDL and only stepped down from that role at the December meeting that just happened due to health concerns. DSDL *will* accommodate the use of W3C Schema when that is important to someone's validation requirements. DSDL has no purview to make any part of W3C Schema an ISO standard, but there are no restrictions to referring to it or accommodating the use of it in the technologies that are developed. www.oasis-open.org /archives/office/200301/msg00002.html   (334 words)

xmlhack: XML 2003 session report: News from the world of DSDL The main input is Schematron, and it has been decided that in effect, DSDL Part 3 will present the evolution of Schematron. An example of what DSDL Part 3 will add to Schematron is extension so that not only XPath 1.0 is supported, but also expressions taken from other languages such as EXSLT, XPath 2.0, XSLT 2.0, and even XQuery 1.0. DSDL members in attendance reassured him that exclusion is not the intention, and expressed a willingness to address concerns about the openness of the project. www.xmlhack.com /read.php?item=2120   (814 words)

The Cover Pages: Rick Jelliffe on NRL and DSDL (Defaults, PSVI) The general ISO DSDL framework is expected to provide various kinds of transformation operations, which should cope with Chris' request. The general reason for this is a belief (shared by most of the instigators of the inidividual schema languages that are being standardized in ISO DSDL) that document transformation (such as adding defaults) and validation are different things and should be disentangled. The problem with defaults values as part of schema languages is that they mean that in order to be sure of the infoset of a document, you have to be sure that the document has been validated. xml.coverpages.org /JelliffeDSDL200306.html   (863 words)

xmlhack: ISO DSDL on the move Document Schema Definition Languages (DSDL) is a project of the ISO/IEC JTC 1/SC34/WG1 working group chaired by Charles Goldfarb. This stage is similar to a W3C "Proposed Recommendation" and the specification should be approved as a final ISO standard within a period of two months. DSDL has also advanced the definition of the remaining parts and several of them should lead to publications during the next meeting at XML Europe 2003. www.xmlhack.com /read.php?item=1842   (248 words)

ISO/IEC JTC 1/SC34 N363 (Draft) DSDL brings together multiple schema languages into a single framework that allows them to work together. That is, DSDL alows specific parts of an XML document to be extracted and then validated. Specifically, when a DSDL framework is represtented by an XML document, it may reference to or contain descriptions in DSDL VCSL. www.y12.doe.gov /sgml/sc34/document/0363.htm   (1100 words)

ISO DSDL Interoperability Framework Still work in progress, the ISO DSDL Interoperability framework is a specification defining the flow of processes involved in the validation of XML documents and document fragments using one or several schema languages. DSDL is proposing a set of specifications which will include a framework, several schema languages (including Relax NG and Schematron), a datatype system and other pieces needed for document validation. DSDL is chaired by Martin Bryan and its editors include James Clark, Murata Makoto, Rick Jelliffe, Martin Bryan, Diederik Gerth van Wijk, Ken Holman and myself). www.idealliance.org /papers/dx_xmle03/papers/02-02-03/02-02-03.html   (2510 words)

DSDL This document is submitted as originally supplied and although the User Requirements are contained in an annex which is marked as normative, the UK does not consider that these requirements, which are instructions to the Project Editor, should remain as normative requirements on the users of the published standard. This document was included in the NWI comments, but the U.K. intended to have it distributed separately in its entirety to serve as a base document for further development. While the W3C XML Schema Definition language (XSD) does allow data types to be used to validate the contents of SGML elements and values of attributes, it does not allow the relationships between the values of different attributes and contents of elements to be validated. www.y12.doe.gov /sgml/sc34/document/0264.htm   (1440 words)

in030111, V1 Annual Report for the period October 2001 to February 2003 DSDL allows multiple schemas, written in multiple schema languages that establish different kinds of constraints, to apply concurrently to a single instance document. DSDL also standardizes several such schema languages, including RELAX NG and Schematron, and methods for specifying datatypes in DTDs and schemas. DSDL has resulted in greatly increased participation in WG 1 in the past year. www.ncits.org /archive/2003/in030111/in030111.htm   (2202 words)

California Criminal Defense Felony DUI Attorney, Felony Defense Lawyer, Felony Los Angeles, Felony Law Firm, Child ... if convicted of a DSDL charge, you can be placed on probation for years and be required to pay fines of up to a thousand dollars (not including a penalty assessment) and serve county jail time of up to six months. However, there are ways to defend and/or reduce a DSDL charge, as well as minimize the potential consequences of a conviction. Even though a DSDL charge may not be a serious criminal charge, the charge itself can be a very stressful ordeal, let alone a conviction. www.wklaw.com /areas_driving_suspended_license.html   (522 words)

SUMMER 93   (Site not responding. Last check: 2007-10-09) The purpose of DSDL is to coordinate the development of common databases within the Division and facilitate the sharing of spatial data, techniques, and programs with other USGS offices across the wide area network. Rather than seek to create a single centralized repository of spatial data, DSDL is designed with the recognition that the most valuable holdings of data and techniques are distributed in many offices across the country. An important advantage of DSDL's distributed repository architecture is that custody of specific data sets will be explicitly assigned, thereby delegating ownership and maintenance of the data and programs to the source of the data. nris.state.mt.us /gis/gisnews/sum93.html   (3135 words)

Cover Pages: Document Schema Definition Languages (DSDL) DSDL initially was used as an abbreviation for Document Schema Definition Language; the name was later changed to Document Schema Definition Languages to signify the closely related set of languages. The DSDL standard is being published as a multi-part specification; it "brings together multiple schema languages into a single framework that allows them to work together." The DSDL Validation Candidate Selection Language (VCSL) is an "XML-based language for controlling selection of validation candidates. DSDL allows specific parts of an XML document to be extracted and then validated; different schema languages and validators may be applied to different candidates. xml.coverpages.org /dsdl.html   (8201 words)

Formalizing the semantics of a DSDL   (Site not responding. Last check: 2007-10-09) The formal semantics of a DSDL is defined in terms of PacSoft's algebraic design language (ADL) [11][10]. This semantics gives the DSDL a computational interpretation in which the relations between the principal concepts of a design abstraction are formalized. Each operator of the abstract syntax of a DSDL is given a computational interpretation by a semantic function. www.cse.ogi.edu /PacSoft/publications/triada/node4.html   (444 words)

XML and Web Service Glossary: DSDL (Document Schema Definition Languages) DSDL is a framework under which several XML Schema Languages are combined. The idea of DSDL is to modularize validation of XML documents, in the sense that for different aspects of validation, different XML Schema Languages can be used. The reasoning behind this approach is that no single XML Schema Language can match all possible applicatio requirements, and rather than creating a very complex and hard to handle XML Schema Language, it makes more sense to create smaller, specialized XML Schema Languages, which are easier to learn, handle, and implement. dret.net /glossary/dsdl   (271 words)

Designing a DSDL   (Site not responding. Last check: 2007-10-09) A DSDL is defined by a computer scientist in consultation with a domain expert. The issues are illustrated with specific examples from the DSDL for the message translation and validation domain (MTV), which is described in greater detail in Section 5. The second is the preliminary definition and informal semantics of the DSDL [20]. www.cse.ogi.edu /PacSoft/publications/triada/node3.html   (417 words)

ISO DSDL Overview The compact syntax for RELAX NG should be included to DSDL part 2 as an addendum and is strictly equivalent to the XML syntax. Diederik Gerth van Wijk has recently produced a draft of DSDL Part 7 focusing on the definitions of character properties and character sets which may be seen as a more advanced way of defining CRX “charrep” attribute. DSDL Part 9 is for these people who would like to rely on years of usage of DTD s without loosing all of the goodies of newer schema languages. idealliance.org /papers/dx_xmle04/papers/03-01-02/03-01-02.html   (2522 words)

3. DSDL Versus Operating System. Unwalla and Kerridge. BNCOD10.   (Site not responding. Last check: 2007-10-09) The DSDL naturally expresses the partitioning of data by content over the data storage. This has the advantage that the search space of a query can be reduced if a predicate in the query refers to a column which is used to partition the data. A partial DSDL specification, relating to our example partitioning (figure 4) discussed later, is shown in figure 6. www.techscribe.mirai.co.uk /bncod/dsdlvos.htm   (535 words)

Cover Pages: Mailing List and Web Site for ISO's Document Schema Definition Language (DSDL). DSDL [ISO/IEC 19757] is a relatively new project under International Organization for Standardization/International Electrotechnical Committee, Joint Technical Committee 1, Subcommittee 34, Working Group 1. Two kinds of integrated specifications are included: specifications for describing aspects of validity of a document, and rules for combining and packaging a collection of processes applicable to the task of validating a document. This integration makes DSDL applicable to both business and publishing applications of structured information resources."

Re: DSDL part 9: new namespace declarations not needed as part Re: DSDL part 9: new namespace declarations not needed as part If DSDL chooses to ratify a namespace declaration form which exhibits indefinite scope, it must also either specify that such documents are non-conformant, or specify that such documents are not permitted to depend on attribute default values for namespace declarations, but must include all namespace declarations in the document entity.

Diary for vdv There are still a number of limitations (includes and external refs, class names and datatypes others than Relax NG builtin "string" and "token" and some validity checks of the schemas themselves are not implemented yet) but the validator passes the 213 tests of the test suite corresponding to what is already implemented. XML Europe is over and it has been one of the best conferences I have ever seen, with lot of food for thoughts and subject of stories for xmlhack and XMLfr...
