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”

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

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

Which led us to write this…

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/procedimiento.pdf

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…

From fields to atributes

ePSIplus Thematic Meeting: Information Management Standards and Data Quality “PSI Asset Registers and Metadata”

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”

Our database asset register II

It includes a reasonable amount of databases (500 something…) covering all the ministries

We think it’s good enough to became the base of an exhaustive (government funded) national database asset registry.

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

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”

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 it’s content, they are highly informative

ePSIplus Thematic Meeting: Information Management Standards and Data Quality “PSI Asset Registers and Metadata”

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”

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”

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”

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”

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”

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

Concluding…

I’m not certain on the limits of the CORE and the Extra metadata

I’m not certain on which ones would have to be included in both categories

But: I’m sure that I would have saved myself 100 hundred hours of thought if anyone had done this before (and I would be thankful)
