<!--
This file is used as a persistent data store for helper application
information about both MIME type and protocol scheme helpers.
The root of the data are the two containers
<RDF:Seq about="urn:mimetypes:root"/> and <RDF:Seq about="urn:schemes:root"/>.
These contain one <RDF:li/> entry per MIME type/protocol. Each <RDF:li/> entry
corresponds to a "urn:<class>:<type>" resource, where <class> is either
"mimetype" or "scheme" and <type> is either a MIME type in "major/minor" format
or a scheme. For example, for HTML we would have "urn:mimetype:text/html",
while for mailto: we would have "urn:scheme:mailto".
Typically, this resource will be in the <RDF:Description/> node which has the
corresponding "about" attribute.
Each "urn:<class>:<type>" resource can have the following properties:
NC:Value - the MIME type or scheme string
NC:editable - a "true" or "false" depending on whether this entry is
editable
NC:description - a description of the type ("HTML Document" for text/html)
NC:fileExtensions - for MIME types, there will be one of these properties
per extension that corresponds to this MIME type,
each one having a single extension as its value.
NC:handlerProp - the way the type should be handled. This corresponds to a
"urn:<class>:handler:<type>" resource. Eg, the way HTML is
handled would be stored in the
"urn:mimetype:handler:text/html" resource.
Each "urn:<class>:handler:<type>" resource can have the following properties:
NC:useSystemDefault - "true" if we should handle per default OS setting,
"false" or not set otherwise
NC:saveToDisk - "true" if the data should be saved to disk, "false" or not
set otherwise.
(Note - if both of these are false, that means "open in helper app")
NC:alwaysAsk - "true" if the user should always be prompted before handling
data of this type, false otherwise.
NC:externalApplication - the preferred helper application to use for this
type. This corresponds to a
"urn:<class>:externalApplication:<type>" resource.
NC:possibleApplication - a helper application that can be used for this type.
Since there can be multiple possible applications,
there can be multiple assertions in the graph with
this property for a given handler resource.
Each "urn:<class>:externalApplication:<type>" resource, and each resource
that represents a possible application, can have the following property:
NC:prettyName - the "pretty name" of the application ("Acrobat Reader" for
/usr/bin/acroread, eg).
If the resource represents a local application, then it can have the following
property:
NC:path - the path to the application on the local filesystem, for example
/usr/bin/test or C:\windows\system32\cmd.exe.
If the resource represents a web application, then it can have the following
property:
NC:uriTemplate - a URI pointing to the web application to which the type
should be handed off, with %s in the template representing
the place where the content should be inserted. For example,
here is a URI template for a service that lets you email
an address in a mailto: link:
http://www.example.com/sendmail?link=%s
