OLAC or the Online Audiovisual Catalogers were one of the test partners for the RDA Test. Just recently they shared their results and questions that came up during the test.
The Online Audiovisual Catalogers/Music Library Association (OLAC/MLA) group
(http://www.olacinc.org/drupal/?q=node/432) that participated in the U.S.
national libraries’ test of RDA has published summaries of many of our wiki-
and email-based discussions. These reflect our experiences as we tried to
apply RDA to music and audiovisual materials. The summaries are grouped as
1. Major issues related to the use and construction of access points, especially expression access points:
2. Other unresolved issues for further investigation, discussion and follow-up:
3. Issues that we thought were satisfactorily resolved:
The summaries describe our discussions and note issues that we hope to
address in the future. They are not meant to be the official position of
either MLA or OLAC nor do they necessarily represent the opinion of all the
participants. We hope they will be useful to others trying to implement RDA
for music and audiovisual materials
