2. AACR2 1978 – with revisions expansion of the original AACR from 1967
published jointly by the American Library Association Canadian Library Association UK Chartered Institute of Library and Information Professionals (CILIP)
Used in or an inspiration in several countries around the world
But:
not designed for the digital environment
did not take into account the conceptual FRBR-models – consolidated version and renamed as IFLA-LRM (Library Reference Model) – –

3. AACR2  AACR3?
A new version: AACR3? – the plan changed in 2005 A whole new approach? – RDA (developed published first version 2010) –

4. What is RDA?
is a package of data elements, guidelines, and instructions for creating library and cultural heritage metadata that are well-formed according to international models
is designed to take advantage of the efficiencies and flexibility in data capture, storage, retrieval, and display made possible with new database technologies but can be used with different database structures.

5. What is RDA?
has been developed to support linked data applications and the Semantic Web since 2007.
aims to become international and includes international communities in further development
published online in RDA-Toolkit

6. RDA – internationally
at first RDA was implemented by large institutions in US, Canada, Australia and by British Library
next RDA was implemented in many European countries - mostly national libraries or agencies have taken the lead. A cooperation between German-speaking countries provided the German translation.
RDA Toolkit includes for now French, German, Spanish, Italian, Norwegian, Finnish, Catalan translations

7. RDA – internationally
also translation has been going on in Israel, China, Japan and in the Arab region.
also many countries choose to use the original English text supported by a national profile.
EURIG, European RDA Interest Group - launched 2011, includes members from approximately 30 European countries today.

8. RDA – governance – RDA Board

17. RDA - perspectives
From rules for describing manifestations and accesspoints to
rules describing all entities – for example for persons: gender, nationality etc.
rules decribing the exact kind of relationsship between entities
Meaning:
data are better fit for new datamodels
records not isolated but can evolve over time – for example with new relationships
cooperation and reuse of data in a new perspective – from local to global and from physical to link
wrapping data up in RDF makes library metadata visible and workable among other resources online

18. … training will be needed
in IFLA LRM – the conceptual model
in the terminolgy of the new RDA
in finding your way around
in application profiles and local policies
