Ontology language

In computer science and artificial intelligence, ontology languages are formal languages used to construct ontologies. They allow the encoding of knowledge about specific domains and often include reasoning rules that support the processing of that knowledge. Ontology languages are usually declarative languages, are almost always generalizations of frame languages, and are commonly based on either first-order logic or on description logic.

RDF

The Resource Description Framework (RDF) is a family of World Wide Web Consortium (W3C) specifications originally designed as a metadata data model. It has come to be used as a general method for conceptual description or modeling of information that is implemented in web resources, using a variety of syntax formats.

A collection of RDF statements intrinsically represents a labeled, directed multi-graph. As such, an RDF-based data model is more naturally suited to certain kinds of knowledge representation than the relational model and other ontological models. However, in practice, RDF data is often persisted in relational database or native representations also called Triplestores, or Quad stores if context (i.e. the named graph) is also persisted for each RDF triple. As RDFS and OWL demonstrate, additional ontology languages can be built upon RDF.

XML Schema

This article is about XML schemas in general. For information on the W3C-recommended schema language for XML, see XML Schema (W3C).

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.

OPML

OPML (Outline Processor Markup Language) is an XML format for outlines (defined as "a tree, where each node contains a set of named attributes with string values"). Originally developed by Radio UserLand as a native file format for an outliner application, it has since been adopted for other uses, the most common being to exchange lists of web feeds between web feed aggregators.

The OPML specification defines an outline as a hierarchical, ordered list of arbitrary elements. The specification is fairly open which makes it suitable for many types of list data.

XML

Extensible Markup Language (XML) is a set of rules for encoding documents in machine-readable form. It is defined in the XML 1.0 Specification produced by the W3C, and several other related specifications, all gratis open standards.

XML's design goals emphasize simplicity, generality, and usability over the Internet. It is a textual data format with strong support via Unicode for the languages of the world. Although the design of XML focuses on documents, it is widely used for the representation of arbitrary data structures, for example in web services.

Many application programming interfaces (APIs) have been developed that software developers use to process XML data, and several schema systems exist to aid in the definition of XML-based languages.

As of 2009, hundreds of XML-based languages have been developed, including RSS, Atom, SOAP, and XHTML. XML-based formats have become the default for most office-productivity tools, including Microsoft Office (Office Open XML), OpenOffice.org (OpenDocument), and Apple's iWork.

How to change background colour

Depending on your computer screen our backgrounds may not stretch the entire width of your blog. You can find color codes for several colors to customize your side wrapper color at this website: http://www.htmlgoodies.com/tutorials/colors/article.php/3478921. Simply choose the color you want, copy the code below it and then paste it into your html to replace the existing code. Below is what it should look like. You will be pasting your new code where you see the yellow code bellow.

body {
background:#DEB887;background-image:url( http://i288.photobucket.com/albums/ll175/simplychicblogs/pinkflowers.jpg);background-position: center; background-repeat:no-repeat; background-attachment: fixed;

How to change blog background

Our backgrounds work best if you use Blogger's 'minima' template. First you must sign into to your blog and click on 'customize' at the top of the page. Once you have done that you then need to click on the 'edit html' tab. Scroll down in your html to where you see this:
body {
background:$bgcolor;
margin:0; color:$textcolor; font:x-
small Georgia Serif; font-size/*
*/:/**/small; font-size: /**/small;
text-align: center;
Change that part of the code to say this:

body {
background:$bgcolor;background-image:url(direct link);background-position: center; background-repeat:no-repeat; background-attachment: fixed;

margin:0; color:$textcolor; font:x-small Georgia Serif; font-size/*
*/:/**/small; font-size: /**/small;
text-align: center;

Now all you need to do is choose the background that suits you and copy the link underneath it and then paste it in your html between the parenthesis where it says direct link. Preview your changes and then once you have checked that everything looks right be sure to save your template. Voila!
