OLAC static repository
Les métadonnées décrivant les dépôts de corps sur ce site sont conformes au standard OLAC (Open Language Archives Community, http://www.language-archives.org) basé sur le schéma du Dublin Core <http://dublincore.org> qui comprend officiellement 15 éléments de description auxquels s’ajoutent des raffinements permettant d’en préciser la signification. OLAC a incorporé à ce schéma un mécanisme d’extension qui permet de décrire les ressources linguistiques avec plus de précision. Pour certains éléments il est possible d’ajouter l’attribut xsi:type qui informe quel aspect de l’élément va être précisé, ainsi que l’attribut olac:code qui apporte la précision.
Les métadonnées OLAC du site font l’objet d’un dépôt statique (OLAC static repository, voir http://www.language-archives.org/OLAC/repositories.html) servi par un portail de dépôts statiques (Static Repository gateway) conforme à l’Open Archives Initiative (OAI-SR). Le fichier XML http://crdo.up.univ-aix.fr/olac/CRDOarchive.xml est mis à jour automatiquement chaque jour. Il peut être validé sur http://www.language-archives.org/register/register.php.
OLAC metadata on this site are compiled in a static repository, see http://www.language-archives.org/OLAC/repositories.html) that is harvested by a Static Repository gateway compliant with Open Archives Initiative (OAI-SR). XML file http://crdo.up.univ-aix.fr/olac/CRDOarchive.xml is updated everyday. It can be validated on http://www.language-archives.org/register/register.php.

Dear OLAC participant,
You are receiving this email by virtue of your association with the following archive that participates in OLAC:
Speech and Language Data Repository (SLDR, formerly CRDO-Aix)
(If you do not wish to receive these emails, please notify your OLAC system administrator, webmaster@sldr.org.)
USAGE
These are statistics on the usage of your metadata records by visitors to the OLAC site, for the period 2011-10-01 to 2011-12-31.
- 58 page views - records viewed on OLAC site
- 12 click-throughs - subsequent visits to your site
QUALITY METRICS
OLAC tracks two metrics as primary indicators of overall metadata quality in its aggregated catalog: number of archives with fresh catalogs (that is, updated within the last 12 months) and number of archives with five-star metadata (that is, fully conforming to best practice as agreed on by the community and without known data integrity problems). See http://www.language-archives.org/metrics for the current values of the metrics and a link to the document that explains them. The currency and quality scores for your archive are:
Last Updated: 2012-01-03
Average Metadata Quality: 8.66 (on a 10 point scale)
Overall Rating: 4-stars
Your average metadata quality is good, but could still be improved.
See the metadata quality analysis of your sample record at the following URL for ideas on what could be done to improve the quality of your metadata.

INTEGRITY PROBLEMS
Congratulations, there are no known integrity problems in your metadata.
