An XML schema is a description of a type of XML document, typically expressed in terms of constraints on the structure and content of documents of that type, above and beyond the basic syntactical constraints imposed by XML itself. These constraints are generally expressed using some combination of grammatical rules governing the order of elements, Boolean predicates that the content must satisfy, data types governing the content of elements and attributes, and more specialized rules such as uniqueness and referential integrity constraints.
There are languages developed specifically to express XML schemas. The Document Type Definition (DTD) language, which is native to the XML specification, is a schema language that is of relatively limited capability, but that also has other uses in XML aside from the expression of schemas. Two more expressive XML schema languages in widespread use are XML Schema (with a capital S) and RELAX NG.
The mechanism for associating an XML document with a schema varies according to the schema language. The association may be achieved via markup within the XML document itself, or via some external means.
Extensible Markup Language (XML) is a markup language that defines a set of rules for encoding documents in a format which is both human-readable and machine-readable. It is defined by the W3C's XML 1.0 Specification and by several other related specifications, all of which are free open standards.
The design goals of XML emphasize simplicity, generality and usability across the Internet. It is a textual data format with strong support via Unicode for different human languages. Although the design of XML focuses on documents, it is widely used for the representation of arbitrary data structures such as those used in web services.
Several schema systems exist to aid in the definition of XML-based languages, while many application programming interfaces (APIs) have been developed to aid the processing of XML data.
As of 2009, hundreds of document formats using XML syntax have been developed, including RSS, Atom, SOAP, and XHTML. XML-based formats have become the default for many office-productivity tools, including Microsoft Office (Office Open XML), OpenOffice.org and LibreOffice (OpenDocument), and Apple's iWork. XML has also been employed as the base language for communication protocols, such as XMPP. Applications for the Microsoft .NET Framework use XML files for configuration. Apple has an implementation of a registry based on XML.
The word schema comes from the Greek word σχήμα (skhēma), which means shape, or more generally, plan. The plural is σχήματα (skhēmata). In English, both schemas and schemata are used as plural forms.

Students learn the fundamentals of XML and its derivatives, including DTD, SVG, XML Schema, XPath, XQuery, XSL-FO, and XSLT. Students also gain experience with programmatic interfaces to XML like SAX and DOM, standard APIs like JAXP and TrAX, and industry-standard software like Ant, Tomcat, Xerces, and Xalan. The course acquaints students with J2EE, including JavaServer Pages (JSP) and Java Servlet, and also explores HT...

What is an XSD file An XSD ( XML Schema Definition Language) file defines the structure of the XML file, i.e which elements in which order, how many times, with which attributes, how they are nested, etc. Without an XSD, an XML file is a relatively free set of elements and attributes. Steps to validate an XML file using XSD file. Step 1 : Create a new Console application. Name it Demo. Step 2 : Add a new XML Schema file to...
StitchDragon.com website and FMWebCMS database Content Management System. See the schema graphically with a brief look under the hood at the Relationships. This project took 5 years to learn the technology and another 3 years to program the FMWebCMS in about 500 builds to the current version 4.5, build 113. Technology: FileMaker Pro & FileMaker Server Advanced, LAMP eCommerce, FileMaker Custom Web Publishing & FX.php, PHP, MySQL, Pear, Pearl, Ruby & Python, HTML, XHTML, DHTML, CSS, XML & XSLT, XML with DOM and Ajax, REST & SOAP, Smarty Templating, Movable Type Blogs, Java, JavaScript, & Flash ActionScript, HTML eMail, Shopping Carts, eCommerce, VeriSign, MIVA Merchant, PayPal integration, etc. The FMWebCMS can build a website in 8 hours that would probably take a month to program in a nor...
After years of being the next big thing, XML has reached translators everywhere as customers start using authoring- and content management systems to manage and publish their content. While most users are able to process XML files reasonably well, for some users XML remains a black box. The goal of this workshop is to address the reservations towards XML that some users may have. In order to support clients and translators in their efforts to minimize their concerns towards XML the following questions will be addressed (among others): • What is XML and why is it used? • What is the relation between XML files, DTD, Schema and the configuration of the CAT Tool? • What tools are available to support the user when working with XML files? The goal of the workshop is to provide the participants ...

A bit of history and demonstration into the XNAT Search Engine, its underlying XML schema, and how to manipulate that schema to query XNAT. Presenter: Tim Olsen Date: June 28, 2012
Abbot: a Conversion Tool for Text Interoperability Abbot is a tool designed to convert dissimilar collections of XML texts into a common interoperable form. Abbot's key feature is the ability to read an XML schema file and output procedures to convert source files into a valid form that is consistent with the target schema. Abbot's schema-harvesting procedures focus on TEI, but it is extremely flexible and format agnostic. Abbot makes no particular judgment or demand concerning the type of interoperability sought. It can transform texts into any XML schema.
Quello che mi sembra di aver capito in questi 3 anni a Milano. Sono scappata dalla Francia dove ho subito un impianto RFID contro la mia volontà. E' avvenuto il 3 luglio 2009 una notte in cui una persona che aveva le chiavi di casa mia ha permesso l'accesso a sconosciuti e poi è scomparso dalla mia vita. Di quella notte ricordo solo di aver spento il computer e di essere andata a dormire subito dopo, erano circa le 2 di notte. Poi non ricordo nulla, se non di essermi svegliata molto tardi e con la faccia gonfia, un grande mal di testa e una sensazione di confusione durata qualche ora, lui era in casa, quando mi sono addormentata non c'era, né ho sentito il cane abbaiare quando è arrivato. La mattina mi ha pregata di accompagnarlo al treno, ha giustificato la sua presenza dicendo che era pa...
