RDA implementation is scheduled for March 31, 2013. Testers of RDA recommended improvements like rewriting instructions in plain English and ensuring community involvement. Differences from AACR2 include lack of abbreviations, more transcription of what is seen, and new fields in MARC like 336, 337, 338 for content/media/carrier types. Linked data and semantic web approaches may make relationships between works more explicit over time. Preparing for RDA involves decisions about cataloging workflows and training.
