Title: Piero Attanasio mEDRA: the European DOI agency
1Piero AttanasiomEDRA the European DOI agency
The DOI as a tool for interoperability between
private and public sector Athens, 14 January
2005
2Summary
- Very shortly What the DOI is and what mEDRA is
- The DOI and the public sector some experiences
- When the DOI may help
- (one example and a general model)
- and when may not.
3The DOI is a standard identifier
www.medra.org
mEDRA
- DOI has a similar role for e-content trade like
the Bar code has in commerce of tangible goods
it facilitates interoperability between the
information systems of parties. - For this reason
- The longer the value chain is,the higher the
value of DOI
4The DOI Metadata
www.medra.org
mEDRA
The DOI is accompanied by metadata describing the
identified entity
- Metadata schemas are required for different
Applications Profiles (APs) - Each schema includes a minimum set of metadata
(kernel metadata) - and additional metadata appropriate for the
application profile. These last includes
descriptive metadata (related to the genre of
the resources) and service and administrative
metadata (related to applications)
5DOI resolution system
www.medra.org
mEDRA
The DOI is supported by a resolution system that
make DOIs actionable in the Internet
- The underlying technology is the Handle System
produced by CNRI (USA) - Handle is a resolution system i.e. a tool to
resolve a number to a source of information
(typically a URL). In some extent it belongs to
the n2l (urn to url) tecnologies - Handle allows multiple resolution i.e. a DOI can
point to more than one source of information
6Resolution vs Identification
www.medra.org
mEDRA
Remind that what the DOI identifies and what
the DOI resolves to are two different concepts
Resolution 1
Resolution 2
DOI
identification
Resolution 3
Resolution 4
Identified entity
7Resolution vs Identification
www.medra.org
mEDRA
It is also possible that DOI does not resolve to
the identified entity
Resolution 1
DOI
identification
Resolution 2
Resolution 3
Identified entity (e.g. a book)
8What is mEDRA?
www.medra.org
- mEDRA is a company created by AIE and Cineca to
manage the DOI registration at European level - It is an example of public (Cineca) private (AIE)
partnership - It was born after an eContent project
- It is based in Italy but operates across Europe,
directly and through forthcoming sub-agencies
9The DOI and the public sector
www.medra.org
- TSO in UK is a registration agency that assigns
DOIs to PSI - The Office of Publication of the European Union
has been recently (July 2004) appointed as DOI-RA
for publications of EU organisations - The OECD (through TSO) and the World Bank
(through Crossref) started registering DOIs on
their content - Some national libraries joined the International
DOI Foundation in last two years
10mEDRA and the public sector
www.medra.org
- The mEDRA early adopters are both in the private
and in the public sector - In Italy
- CNIPA (the Italian authority for IT in the public
sector) participated since the beginning to the
pilot project - Some universities are starting DOI registration
11When assigning DOIs to PSI is useful?
www.medra.org
- When the value chain is long and complex
- Therefore
- When the PSI is re-used in a private value chain
- When the PSI should interoperate with private
sources
12One example the Italian portal of medicine
content
www.medra.org
- It is a project to aggregate content produced in
Italy for medicine, including - Journal articles
- Books and electronic monographs
- Learning objects for medical training
- It is open to content produced by private
publishers and public institutions
13The architecture of the service

14A model for re-use of PSI

Public sector

Rights negotiation
Access
15Which could be the role of the DOI?
www.medra.org
- Metadata may include rights information for PSI
- The DOI may guarantee persistence and facilitate
up-grading of information used in private value
chain - Standardisation facilitates the creation of
portals for content to be negotiated
16When the DOI does not help
www.medra.org
- If the value chain is short
- When the public sector provides directly
information to citizens - When there is no need to interoperate with
private sources - In such cases any alternative system may work
