Schema for Object Oriented XML , or SOX , is an XMLschema language developed by Commerce One . In 1998 a SOX specification was submitted to the World Wide Web Consortium and published as a W3C Note. A revised version, SOX 2.0, was published as a W3C Note in 1999. SOX was one of several predecessors of the W3C s XMLSchemaW3CXMLSchema language. After the publication of XMLSchema, SOX continued to be supported by Commerce One until the company s bankruptcy in late 2004. The patents for SOX and other Commerce One technologies were purchased by Novell, Inc. in December 2004, reportedly in an effort to prevent them from being exploited by unrelated companies whose primary business is filing patent related lawsuits. http www.iht.com articles 2005 05 02 business novell.php See also XMLSchemaW3CXMLSchema Simple Outline XML another XML technology with the initials SOX External links http www.w3.org TR NOTE SOX SOX schema language W3C Note Soft eng stub Category XML Category XML based standards ja Schema for Object Oriented XML ... more details

Context date October 2009 XML Data Reduced XDR was a schema language for specifying and validating XML documents. In January 1998, Microsoft , the University of Edinburgh and others submitted a proposal for an XMLschema language called XML Data to the World Wide Web Consortium. XML Data Reduced was a subset of XML Data, with some corrections and amendments submitted in July 1998. ref http www.ltg.ed.ac.uk ht XMLData Reduced.htm XML Data reduced ref The XMLSchemaXMLSchemaW3C effort in the World Wide Web Consortium W3C received several other proposals, and while the final result has some similarities to the XDR proposal, it is significantly different. XDR was implemented in SQL Server 2000 and Biztalk Server 2001. Once the XMLSchema Definition was finalised in 2001, Microsoft products and tools added support for it, and XDR was gradually phased out.

As expressed in semi natural language where S is the name of the sentence abbrivated to S S is true if and only if S Example snow is white is true if and only if snow is white. The inductive definition By using the schema one can give an inductive definition for the truth of compound sentences. Atomic sentences are assigned truth value s disquotationally. For example, the sentence Snow is white is true becomes materially equivalent with the sentence snow is white , i.e. snow is white is true if and only if snow is white. The truth of more complex sentences is defined in terms of the components of the sentence A sentence of the form A and B is true if and only if A is true and B is true A sentence of the form A or B is true if and only if A is true or B is true A sentence of the form if A then B is true if and only if A is false or B is true see material implication .

Without being specific to a particular database management product, it is in terms of either relational tables and columns, object oriented classes, or XML tags. This is as opposed to a conceptual data model , which describes the semantics of an organization without reference to technology, or a physical data model , which describes the particular physical mechanisms used to capture data in a storage medium.

In the American National Standards Institute ANSI four schema architecture, the internal schema was the view of data that involved data management technology. This was as opposed to the external schema that reflected the view of each person in the organization, or the conceptual schema that was the integration of a set of external schemas. Subsequently the internal schema was recognized to have two parts The logical schema was the way data were represented to conform to the constraints of a particular approach to database management. At that time the choices were hierarchical and network. Describing the logical schema, however, still did not describe how physically data would be stored on disk drives. That is the domain of the physical schema . Now logical schemas describe data in terms of relational tables and columns , object oriented classes , and XML tags . A single set of tables, for example, can be implemented in numerous ways, up to and including an architecture where table rows are maintained on computers in different countries.

Orphan date February 2009 att April 2011 The XML Protocol XMLP is a standard being developed by the W3CXML Protocol Working Group to the following guidelines, outlined in the group s charter An envelope for encapsulating XML data to be transferred in an interoperable manner that allows for distributed extensibility. A convention for the content of the envelope when used for RPC Remote Procedure Call applications. The protocol aspects of this should be coordinated closely with the IETF and make an effort to leverage any work they are doing, see below for details. A mechanism for serializing data representing non syntactic data models such as object graphs and directed labeled graphs, based on the data types of XMLSchema. A mechanism for using HTTP transport in the context of an XML Protocol. This does not mean that HTTP is the only transport mechanism that can be used for the technologies developed, nor that support for HTTP transport is mandatory. This component merely addresses the fact that HTTP transport is expected to be widely used, and so should be addressed by this Working Group. There will be coordination with the Internet Engineering Task Force IETF . See Blocks Extensible Exchange Protocol Further, the protocol developed must meet the following requirements, as per the working group s charter The envelope and the serialization mechanisms developed by the Working Group may not preclude any programming model nor assume any particular mode of communication between peers. Focus must be put on simplicity and modularity and must support the kind of extensibility actually seen on the Web. In particular, it must support distributed extensibility where the communicating parties do not have a priori knowledge of each other.

XML Base is a W3C recommendation World Wide Web Consortium recommended facility for defining base Uniform Resource Identifier URI s for parts of XML documents. XML Base recommendation was adopted on 2001 06 27. The attribute xml base may be inserted in XML documents to specify a base URI other than the base URI of the document or external entity. The value of this attribute is interpreted as a URI Reference as defined in RFC 3986 IETF RFC 3986 . It serves the function described in section 5.1.1 of RFC3986, establishing the base URI or IRI for resolving any relative references found within the effective scope of the xml base attribute. In namespace aware XML processors, the xml prefix is bound to the namespace name http www.w3.org XML 1998 namespace as described in Namespaces in XMLXML Names . Note that xml base can be still used by non namespace aware processors.

XML Encryption , also known as XML Enc, is a specification, governed by a World Wide Web Consortium W3C recommendation, that defines how to encrypt the contents of an XML element. Although XML Encryption can be used to encrypt any kind of data, it is nonetheless known as XML Encryption because an XML element either an tt EncryptedData tt or tt EncryptedKey tt element contains or refers to the cipher text, keying information, and algorithms. Both XML Signature and XML Encryption use the tt KeyInfo tt element, which appears as the child of a tt SignedInfo tt , tt EncryptedData tt , or tt EncryptedKey tt element and provides information to a recipient about what keying material to use in validating a signature or decrypting encrypted data. The tt KeyInfo tt element is optional it can be attached in the message, or be delivered through a secure channel. XML Encryption is different from and unrelated to Transport Layer Security , which is used to send encrypted messages including xml content, both encrypted and otherwise over the internet. It has been reported that this specification has severe security concerns. ref http it.slashdot.org story 11 10 22 0310230 xml encryption broken need to fix w3c standard XML Encryption Broken, Need To Fix W3C Standard Slashdot ref Notes references External links http www.w3.org TR xmlenc core W3C info Category XML Category Cryptography standards Category XML based standards W3C standards web stub es Xml encryption de XML Encryption ru XML Encryption zh XML Encryption hu XML K dol s ... more details
