Why, what were the idea ? 1.Create a data infrastructure, 2.Data + the knowledge products that are produced on the basis of data a) Efficiant access to large volumes of data b) Promote comparative analysis c) Support dissemination of knowledge d) Support the idea that knowledge have to be empirically based e) Create an infrastructure that may grow by its own force

How A distributed model, data stored and maintained locally, modern technology substitute for central institutions One common entrypoint, a portal One common metadata standard, that we were supposed to contribute to One technical solution One common multilingual thesaurus

More hows A requirement was that the user communities participated, allowed themselves to be activated and invested some resources a) Developing a classification of resources b) Use common metadata standard Give bettered semantics / ontology Help solve some language issues Produce more heterogeneous data Produce better quality of data Give better administration of data

Resource promation and integration Tools for publishing and finding data Guidelines for publishing and finding data Access control And there should be room for others, we could go beyond CESSDA

The Portal Metadata is all about communication A set of tools + an idea: Data is the core that facilitates a ”conversation” Technology, functionality Multilingual thesaurus Metadata standard

Activity in numbers manhours 40+ persons 41 deliverables 3 workshops 7 meetings 15 presentations 33 teleconferences The portal contains: –3000 studies – objects

The Portal We have data identified at 3 levels: Study, Variable group and Variable Study Variable group Variable Free text search X X X CESSDA Classification X ELSST 1 X ELSST 2 X X X Archives X NUTS X

The Portal The free-text search give the user the possibility to specify a completely free search term. If you search for “sausage”, you will presently get 1 hit, at variable level. This term (sausage) seems not to be in ELSST (yet) If you search for “radio”, you get hits. “Radio” is a word used in many languages (all languages with data on the servers). If you search for “fjernsyn”, you get hits. “Fjernsyn” is the Norwegian word for television. If we expand the word “fjernsyn” to the equivalent in other languages, we get hits. Such an expansion checks against ELSST and picks up the translations. Common for all: Searching in free text may give hits at all three levels of data. When browsing, some terms (keywords) are automatically translated back to the user. The Cessda classification is a controlled vocabulary used for the DDI element topcClass, which is at study level.. If this term is systematically used, we can set up a catalog structure. Then a study typically could be published in more than one catalogue. ELSST1 is a finer granulation then the Cessda classification, it gives the impression of an alphabethical sorted list of keywords, and it gives easy access to translations and the systematic structure with synonyms and related terms. But it works at study level,.

The Portal ELSST1 is a finer granulation then the Cessda classification, it gives the impression of an alphabethical sorted list of keywords, and it gives easy access to translations and the systematic structure with synonyms and related terms. But it works at study level, ELSST2 matches on a few key text fields (title, abstract, keywords, subject, etc.) The most important thing about the etc is that it searches DDI elements at three different levels, study, variable group (name) and variable level (label, text, concept). Archives actually lists the servers under the portal, for every server studies are listed sorted alphabethic The NUTS list gives units at different levels of NUTS, the search could use coordinates inserted in GeoBndBox. I don’t know how this is done (which DDI-elements are used).

Functionality: Geo-Chartography Finding data by geography Europe a mixture of political, administrative and statistical units Code, Name, Coordinates Problem: Publish

Functionality: Comparability

Functionality: Naming Conventions Objective: For a user to be able to update (metadata) 1. Add to metadata of a study 2. Use could also lead to changes, corrections, updates Distinguish between two components of an identification: Identifier (static) – version code (dynamic) Elements that we identify consist of data and metadata Elements could also be a complex mixture of instances that make up a study And studies could be part of series

Functionality: Naming Conventions Series Study Instance 1Instance 2 Data Metadata All this described as a complex set of modules Data from data producers Metadata from archives
