1 Metadata for Asset Registers, a pan-european proposal Rodrigo Sánchez Jiménez Publidoc - UCM ePSIplus Thematic Meeting: Information Management Standards and Data Quality PSI Asset Registers and Metadata

2 Introduction Want to talk about the posibility of creating a pan-european metadata standard for PSI. And to explain our ideas on this issue. I say our ideas because I represent a research group -> Publidoc UCM ePSIplus Thematic Meeting: Information Management Standards and Data Quality PSI Asset Registers and Metadata

3 PUBLIDOC – UCM. Research group Our main project for the last few years has been related with the analysis of PSI in Spain and its adaptation to the european model Original Goals of the project: – Analysis of types of PSI resources – PSI management practices – PSI re-use perspectives and European Directive implementation ePSIplus Thematic Meeting: Information Management Standards and Data Quality PSI Asset Registers and Metadata

4 Which led us to write this… ePSIplus Thematic Meeting: Information Management Standards and Data Quality PSI Asset Registers and Metadata

6 New perspectives… We found the most interesting part was that of the databases We analyzed the databases of the General Administration of the State and began to gather information for our study This led us to create describing practices and protocols which we summarized in this document http://crom.eubd.ucm.es/~publidoc00/bdpublidoc/pro cedimiento.pdf http://crom.eubd.ucm.es/~publidoc00/bdpublidoc/pro cedimiento.pdf http://crom.eubd.ucm.es/~publidoc00/bdpublidoc/pro cedimiento.pdf ePSIplus Thematic Meeting: Information Management Standards and Data Quality PSI Asset Registers and Metadata

7 New perspectives… This set of descriptive fields was not thought of as metadata, but as a way of holding together all the information for a technical analysis London Meeting We then thought of creating a asset register, so we had to make certain changes… ePSIplus Thematic Meeting: Information Management Standards and Data Quality PSI Asset Registers and Metadata

8 From fields to atributes ePSIplus Thematic Meeting: Information Management Standards and Data Quality PSI Asset Registers and Metadata

9 Our database asset register We selected some of the fields and put together all the records in a Web Site that looks like this … ePSIplus Thematic Meeting: Information Management Standards and Data Quality PSI Asset Registers and Metadata

10 Our database asset register II It includes a reasonable amount of databases (500 something…) covering all the ministries We think its good enough to became the base of an exhaustive (government funded) national database asset registry. ePSIplus Thematic Meeting: Information Management Standards and Data Quality PSI Asset Registers and Metadata

11 Moving on towards the european standard … I RIGA After Riga we began to think of the posibility of an european standard, but… – We have already been told that this arises some schepticism – Standaraising is in itself a difficult task – We should map to Dublin Core ePSIplus Thematic Meeting: Information Management Standards and Data Quality PSI Asset Registers and Metadata

12 Moving on towards the european standard …II ePSIplus Thematic Meeting: Information Management Standards and Data Quality PSI Asset Registers and Metadata

13 Types of elements Plain elements (properties) Normalized elements – Encoding schemes – Sets of controlled values Qualified elements (sub-properties) Ranged elements (properties with range) ePSIplus Thematic Meeting: Information Management Standards and Data Quality PSI Asset Registers and Metadata

14 Plain elements (properties) Provide us with a lot of text. Text is good for retrieval – Search engines and other Information Retrieval tools are usualy dependant on statistical features of resources – If you are going to be crawled these elements are essential People can easily understand its content, they are highly informative ePSIplus Thematic Meeting: Information Management Standards and Data Quality PSI Asset Registers and Metadata

15 Normalized elements Encoding schemes provide for better application use (urls and browsers, ISO language codes…) Sets of controlled values – Provide normalization of key concepts, as in the rights of access and use: Reuse free of charge Reuse not free of charge Reuse possible Reuse not possible Reuse possible / only for administration Reuse possible / non-profit purpouses Reuse possible / commercial purpouses – Provide us with the ability of creating filters! Give me Type.genre [statistical data] AND Subject.descriptor [crime] ePSIplus Thematic Meeting: Information Management Standards and Data Quality PSI Asset Registers and Metadata

16 Normalized elements Sets of controlled values – Allow selective information disemination, profile based retrieval, sindication (RSS, ATOM…) Channels for subjects or genres Stablishment of profiles based on both semantics and structure – Improve precision of results if properly used by Information or Data Retrieval tools ePSIplus Thematic Meeting: Information Management Standards and Data Quality PSI Asset Registers and Metadata

17 Qualified elements We have added lots of them – To be able to map to DC – To be able to make specific PSI descriptions (not general ones) Increase interoperability with other metadata schemes Allow for different levels of granularity both in description and retrieval ePSIplus Thematic Meeting: Information Management Standards and Data Quality PSI Asset Registers and Metadata

18 Qualified elements Allows us to switch from high recall to high precision results ePSIplus Thematic Meeting: Information Management Standards and Data Quality PSI Asset Registers and Metadata

19 Ranged elements A range is a set of resources that can be associated to the resource being described through the use of a special atribute or metadata element ePSIplus Thematic Meeting: Information Management Standards and Data Quality PSI Asset Registers and Metadata

20 What is all this complexity for??? These are just ways of extending our scheme, but, it might be as well that some of them where compulsory in the basic schema. Asset discovery Informative Value adding ePSIplus Thematic Meeting: Information Management Standards and Data Quality PSI Asset Registers and Metadata

21 Concluding… Im not certain on the limits of the CORE and the Extra metadata Im not certain on which ones would have to be included in both categories But: Im sure that I would have saved myself 100 hundred hours of thought if anyone had done this before (and I would be thankful) ePSIplus Thematic Meeting: Information Management Standards and Data Quality PSI Asset Registers and Metadata
