LDP Core Element Descriptions 

1.      Author or Creator
        Label: CREATOR
The person or organization primarily responsible for creating the
intellectual content of the resource. CREATOR should appear in RFC822
format (http://info.internet.isi.edu:80/in-notes/rfc/files/rfc822.txt).
Preferred format: mailname@site.domain.top (Full Name)

2.      Current Maintainer
        Label: MAINTAINER
The person or organization responsible for publishing the resource in its
current form.  If left blank, this value defaults to CREATOR. (RFC822
format) 

3.      Other Contributor
        Label: CONTRIBUTOR
A person or organization not specified in a CREATOR or MAINTAINER element
who has made significant intellectual contributions to the resource but
whose contribution is secondary to any person or organization specified in
a CREATOR or MAINTAINER element.  (RFC822 format)

4.      Title
        Label: TITLE
The name given to the resource by the CREATOR or MAINTAINER.

5.      Date
        Label: VERSION
Chronological publication information for the resource.  Multiple
instances of this element comprise the resource's revision history.
VERSION is a multifaceted element, consisting of three attributes:
        VERSION.identifier
        VERSION.date
        VERSION.description     
VERSION.identifier consists of a string or number that distinguishes each
revision of the resource from other revisions.  VERSION.date records the
date the resource was made available in the form VERSION.identifier.
(Recommended best practice is an 8 digit number in the form YYYY-MM-DD as
defined in http://www.w3.org/TR/NOTE-datetime, a profile of ISO 8601. In
this scheme, the date element 1994-11-05 corresponds to November 5, 1994.)
VERSION.description summarizes revisions that distinguish
VERSION.identifer from other versions of the resource.

6.      Subject and Keywords
        Label: SUBJECT
The topic of the resource. Typically, this element employs keywords that
summarize the subject or content of the resource.
A controlled vocabulary specific to the LDP SUBJECT is in the process of being
developed via the Open Source Research Team, University of North
Carolina at Chapel Hill. The controlled vocabulary will be an open
contributory project once initiated. 

7.      Description
        Label: DESCRIPTION
A textual description of the content of the resource (e.g., an abstract).

8.      Resource Type
        Label: TYPE
The category of the resource.  For the sake of interoperability, TYPE
should be selected from an enumerated list: 
        HOWTO
        mini-HOWTO
        user's guide
        administrator's guide
        programmer's guide
        installation guide

9.      Format
        Label: FORMAT
The media type of the resource.  FORMAT should be expressed as a MIME type, 
as defined in RFC 2046 (http://info.internet.isi.edu:80/in-notes/rfc/files/rfc2046.txt).
e.g.:  type/subtype.  

10.     Resource Identifier
        Label: IDENTIFIER
A specification of the site and directory in which the resource will be
stored upon publication.  Entries for this field should contain a fully
resolvable URL of the type:
        http://www.ldp.org/docs/howto/resource.html

11.     Source
        Label: SOURCE
A specification of any previous or alternative publication of the
resource.  In most cases values for SOURCE would include a URL.  However,
they might also refer to print material by use of an ISBN or similar
device. 

12.     Language
        Label: LANGUAGE
Language(s) of the intellectual content of the resource. Where practical,
the content of this field should coincide with RFC 1766. See:
http://ds.internic.net/rfc/rfc1766.txt 

13.     Relation
        Label: RELATION
A URL that points to the IDENTIFIER element of another resource.  Each
instance of RELATION links the resource to other resources of similar
domain or style.

14.     Coverage
        Label: COVERAGE
A multifaceted description of the resource's intellectual scope.
Attributes include:
        COVERAGE.geographic     (regional specificity; defaults to none)
        COVERAGE.distribution   (for specific distributions; defaults to none)
        COVERAGE.kernel         (which kernel versions are treated; defaults to all)
        COVERAGE.architecture   (hardware specificity; defaults to none)
        COVERAGE.os             (operating systems covered; defaults to none)
Where practical COVERAGE.geographic should be expressed as an ISO 3166-compliant string  
of two characters.  See http://www.w3.org/International/O-misc-iso3166.html

15.     Rights Management
        Label: RIGHTS
An indication of the copying policy under which the resource is distributed.  Three 
attributes comprise the RIGHTS element:
        RIGHTS.type             (the name of the resource's distribution license)
        RIGHTS.license          (a URL for the license referenced in RIGHTS.type)
        RIGHTS.license.version  (the version number of the resource's license) 
For the sake of interoperability, RIGHTS.type should derive from an enumerated list
of possible values.  A prliminary list of known licenses (culled from 
www.opensource.org/licenses/) is:
        GNU GPL, GNU LGPL, BSD, X Consortium, Artistic, MPL, QPL, IBMPL,
        ASPL, libpng, zlib, IJG JPEG, OPL
