---++ Objects

---+++ OAT.RDFStore(callback, options)

Creates the object. Argument callback is executed every time store's contents change. Available <tt>options</tt> (properties of options object) are:

   * <tt><b>ajaxStart</b></tt> - function to be executed when dereferencing starts
   * <tt><b>ajaxEnd</b><tt> - function to be executed when dereferencing stops

---++ Properties

---+++ OAT.RDFStore::data.triples

All loaded data in a big array of triples (array of arrays).

---+++ OAT.RDFStore::data.all

All loaded data in a complex JSON object, as shown in the Example.

---+++ OAT.RDFStore::data.structured

Loaded data after filters have been applied. Same structure as <tt>data.all</tt>.

---++ Methods

---+++ OAT.RDFStore::addURL(url, onstart, onend)

Dereferences url and adds its contents to store. <tt>onstart</tt> and <tt>onend</tt> arguments are used to override global <tt>ajaxStart</tt> and <tt>ajaxEnd</tt> parameters, respectively.

---+++ OAT.RDFStore::addTriples(triplesArray, url)

Adds an array of triples (triplesArray) to storage. The url specifies the address where these triples originate.

---+++ OAT.RDFStore::addXmlDoc(xmlDoc, url)

Adds an XML document (xmlDoc, fetched byOAT.AJAX.GETfor instance) to storage. The <tt>url</tt> specifies the address where this document originates.

---+++ OAT.RDFStore::getTitle(itemReference)

Returns a reasonable title (falls back to URI) of an item in storage.

---+++ OAT.RDFStore::simplify(string)

Simplifies an URI by removing as much as possible (leaving the part after '#' or '/').

---+++ OAT.RDFStore::addFilter(type, value1, [value2])

Applies a pass filter to store contents. Filter type is specified as one of available constants.

For FILTER_PROPERTY, both 2nd and 3rd arguments should be used: these specify predicate value and object value(only resources having this P and O will pass).

For FILTER_URI, only 2nd argument should be used: this value specifies an URI to be filtered (only resources having this URI as O or S will pass).

---+++ OAT.RDFStore::removeFilter(type, value1, [value2])

Removes a previously set filter; syntax is the same as in <tt>addFilter</tt>.

---+++ OAT.RDFStore::disable(url)

Temporarily disables (removes) all triples originating from URL from the store. URL must be dereferenced.

---+++ OAT.RDFStore::enable(url)

Re-enables previously disabled URL, so its contents are loaded in a store. URL must be dereferenced.
