NAME ^

AxKit::App::Gallery::namespaces - XML namespaces used by AxKit::App::Gallery

DESCRIPTION ^

The RDF files generated by AxKit::App::Gallery use elements from a number of different XML namespaces. They are described in this document.

RDF, http://www.w3.org/1999/02/22-rdf-syntax-ns#

The Resource Description Framework is used to provide structure to the meta information, but says nothing about the actual information.

FOAF, http://xmlns.com/foaf/0.1/

The Friend Of A Friend vocabulary is used for meta data about people and things depicted in images in your galleries. AxKit::App::Gallery writes the following FOAF elements.

foaf:thumbnail

Used as the wrapper element for references to the thumbnails that AxKit::App::Gallery generates.

The default stylesheets support the following elements.

foaf:depicts

Used to link pictures about a person or object to additional pages of information about that person or object.

Dublin Core, http://dublincore.org/documents/dces/

From its web page:

    The Dublin Core metadata element set is a standard for cross-domain 
    information resource description. Here an information resource is 
    defined to be "anything that has identity". This is the definition 
    used in Internet RFC 2396, "Uniform Resource Identifiers (URI): 
    Generic Syntax", by Tim Berners-Lee et al. There are no fundamental 
    restrictions to the types of resources to which Dublin Core metadata 
    can be assigned.

AxKit::App::Gallery writes the following DC elements:

dc:title

A thumbnail's filename

The default stylesheets support the following elements.

dc:creator

Will be displayed as the name of the person responsible for taking the photograph.

dc:subject

Will be treated as a comma separated list of keywords relating to the photograph.

dc:description

Will be displayed as a caption for the photograph (in preference to displaying the photograph's filename).

EXIF, http://impressive.net/people/gerald/2001/exif#

At the time of writing there is no widely agreed upon standard for representing digital image EXIF data in XML. Gerald Oskoboiny has a suggested EXIF namespace, and AxKit::App::Gallery uses this namespace rather then invent a different one.

AAG, http://search.cpan.org/~nikc/AxKit-App-Gallery/xml#

This is a catch-all namespace for any information that needed to be represented in the RDF for which a suitable representation in some other namespace could not be found. I plan to remove all references to this namespace as I become more familiar with available XML vocabularies that can be used for AxKit::App::Gallery.
