An effective namespace conversion connect espace document alone
Consider a purchase order that has a namespace document represented in XML Schema, where the XML Schema bears a data-view:transformation attribute licensing extraction of statements that include namespaceTransformation statements:
4. Playing with GRDDL which have valid XHTML
To help you accomodate brand new DTD-mainly based sentence structure regarding XHTML[XHTML], hence precludes playing with properties out-of overseas namespaces, we explore given that a great metadata character (cf. section seven.cuatro.4.3 Meta tags users regarding [HTML4]).
All round brand of adding a GRDDL denial to a legitimate XHTML file is via indicating the newest GRDDL character in the profile trait of your head feature, and sales given that value of the newest rel feature regarding an excellent link otherwise a good element whose href attribute really worth is an IRI reference one identifies an executable program or program that is anticipated to alter the main cause file to your RDF. This technique is appropriate for use having legitimate XHTML data files and that was constrained by an XML DTD.
An illustration Dublin Key META conversion
Such as, which document follows brand new conventions out-of [RFC2731], plus it clearly spends the newest GRDDL reputation and you may hyperlinks in order to an enthusiastic XSLT sales to RDF/XML so you can laws that the conversion are a loyal rendition:
Numerous changes in the XHTML
An XHTML document may adhere to a number of dialects simultaneously and you will link to one or more GRDDL transformation. Yet not, because the href feature of one’s link and good elements deal with only one IRI reference, numerous cases of this type of issue is employed to assert numerous links:
Rules to have GRDDL that have valid XHTML
Note that the base IRI of an element node in an XHTML document may be influenced by factors such as a base element[HTML4] Retrieval URIRFC3986, etc. See the Base IRI considerations appendix and test cases such as htmlbase1 for further clarification.
5. GRDDL to have HTML Users
XHTML provides the character system to link to this is out-of characteristics and band of legal thinking for those attributes. Just as in namespace data files, a visibility file is effectively become written playing with XHTML that have stuck RDF statements and you will an effective GRDDL transformation to recoup the definition of terms that are appropriate. People words can then be taken inside an XHTML file so you’re able to express profile-mainly based meaning. Because the discussed in using GRDDL having legitimate XHTML, the new GRDDL profile may be used that have XHTML data files to utilize GRDDL semantics over link aspects where value of rel attribute is conversion . This very powerful and flexible apparatus integrates better with microformat pages[MF-RDF-FAQ] which overlay the brand new normally semantically-worst HTML markup.
Adding an excellent GRDDL profileTransformation denial so you can a visibility document is a lot eg including a great namespaceTransformation assertion to help you a great namespace document. To have good dialect outlined from the a valid XHTML profile data, put profile=”” into the direct element to make an association regarding type profileTransformation towards transformation of the dialect.

- subject is actually PDOC , whoever
- predicate is the property < and whose
- target was Texas ,
six. GRDDL Changes
As noted above, each GRDDL transformation specifies a transformation property, a function from XPath document nodes to RDF graphs. This function need not be total; it may have a domain smaller than all XML document nodes. For example, use of xsl:content with terminate="yes" may be used to signal that the input is outside the domain of the transformation.
Builders regarding transformations need to make offered representations when you look at the widely-served platforms. XSLT variation step 1[XSLT1] date me 's the style really generally backed by GRDDL-alert agents at the creating, even when though XSLT2[XSLT2] deployment is expanding. If you are technically Javascript, C, or any other other program writing language can help display changes to possess GRDDL, XSLT are specifically made to fairly share XML to help you XML transformations and has some a good cover properties; XQuery features equivalent qualities to help you XSLT, whether or not entry to XQuery when you look at the GRDDL implementation are quicker extensively implemented during the time of that it writing.
