Linguistic Resources Document
A Linguistic Resources Document (LRD) is an XML document consisting of a set of linguistic resources (dictionaries, cross models, corpora, links to other LRDs, etc.).
This document can be used with apertium-crossdics to indicate which resources (dictionaries and cross models) can be crossed.

Resource
A resource is defined with a set of properties.
<resource> <property name="name" value="apertium-es"/> <property name="type" value="mon"/> <property name="sl" value="es"/> <property name="for-crossing" value="yes"/> <property name="src" value="apertium-es-ca.es.dix"/> <property name="version" value="stable"/> </resource>
Resource properties
Possible values for resources are:
- name: the name of the resource.
- type: the type of resource. Possible values are:
- mon: morphological dictionary.
- bil: bilingual dictionary.
- crp: corpus.
- lrd: link to Linguistic Resource Document.
- cross-model: cross model document.
- sl: source language (for example, in morphological and bilingual dictionaries)
- tl: target language (for example, in bilingual dictionaries)
- src: source (URL or file path)
- file path:
/home/user/apertium-es-ca.es.dix - URL:
http://apertium.svn.sourceforge.net/viewvc/*checkout*/apertium/trunk/apertium-es-ca/apertium-es-ca.es.dix
- file path:
- version: version of the resource (for example, for dictionaries: stable, unstable, pre-aplha, etc).
- ¿more?
Set of resources
It is possible to group a number of resources with the resource-set tag, as follows:
<resource-set>
<name></name>
<description></description>
<resource>
<property name="" value=""/>
...
</resource>
<resource>
<property name="" value=""/>
...
</resource>
...
</resource-set>
This organisation can be useful to group linguistic data from certain language pair.
