Objectives

5

This study has been prepared in the context of

the Interoperability for European Public

Administrations (ISA) Programme and, in

particular A Reusable INSPIRE Reference

Platform (ARE3NA, ISA Action 1.17)

Connecting Geospatial DataThis study should provide:

1. Shared evidence about the current status

in Europe of linked (geospatial) data

related to INSPIRE.

2. An initial common/agreed methodology

and guidelines towards RDF encodings for

INSPIRE

3. Recommendations for how location PIDs

could be governed for INSPIRE and other

relevant activities.


Scope

6

PIDs

Real World Things

Data Sets/Objects

Resources on the web that

contain data about real-world

things

Real-world things such as a river

basin, train station, a country, etc.

Linked Data Principles

1) Use URIs as names for things

2) Use HTTP URIs, so that people can look up those names

3) When someone looks up a URI, useful information should be provided, using the standards (RDF, SPARQL)

4) Include links to other URIs, so that they can discover more things

<<assign>> <<assign>>

<<include>>

PID = A persistent identifier (PI) is a long-lasting reference to a digital object—a single file or set of files.

Noted persistent identifier systems include: Archival Resource Keys (ARKs), Digital Object Identifiers (DOIs),

Persistent Uniform Resource Locators (PURLs), Uniform Resource Names (URNs), and Extensible Resource

Identifiers (XRIs)

Governance refers to the control and

the steering of the decisions on PIDs

Operations is about the processes

and tools needed to run PIDs

Financing is about the resources

needed for the operations and the

architectural updates

Architecture corresponds to a formal

specifications around PIDs

Governance

Preliminary conclusions

Based on available data analyzed until now:

1) Policy is often associated with URI design

patterns and the management of domains.

However, there is definitely more than these

two elements.

2) When a policy exists it isn’t always well

formalized depending on the size and

organizational structure.

3) There seem to be no examples of PID

organizational structures in the context of

INSPIRE and in e-Government.

4) There is a lot of theoretical work about the

“technical side” of persistent identifiers, often

associated with linked data

5) Lack of a holistic picture that integrates the

several GOFA dimensions.

Barriers


1) PIDs governance is an inherently complex

topic given the way that “ICT governance and

management” is done in the different Member

States

2) There is “no silver bullet” for PID governance

PIDs PolicyDefines what and

how can be assigned a PDI

ValidationValidates the

format, location and the uniqueness of

PIDs

RegistrationCreates and registers

PIDs

Redirection Uses persistent PIDs

to redirect to the

desired Web resource

Long Term Preservation Archives fullback copies of “dead”

resources

Business CaseJustifies the investment in persistent identifiers

Cost ModelDefines the allocation of costs and charges associated with the provision of persistent PIDs.

PIDs Organisational structureDefines who has the authority and control (planning, monitoring and enforcement) over the management of PIDs

Service ModelDescribes the set of services that will benefit from the use of persistent PIDs, this encompasses both data and metadata about services

1) There are no formalized business cases for

PIDs – we believe that the interest in linked

data is sometimes enough:

e.g. John Sheridan, Head of

Legislation Services “A business

case for using linked data would like

making a business case for using

electricity.”

2) There seems to be no cost model for PIDs.

For Linked Data or the implementation of

INSPIRE, when they can be found, they are

very different from one case to the other.

Below are a few examples:

Development costs, Maintenance costs, Promotion

costs – Linked Data

Operating costs of the IT infrastructure, Production of

interoperability Business model for the implementation

of INSPIRE, IT structure Processing of spatial data,

Personnel – INSPIRE Germany

Barriers

1) No clear understanding on the investment

needed to set up PIDs.

1) The domain owner is implicitly considered

to be responsible for registration and

validation

2) There is little discussion about long term

preservation and most papers mention 303

Redirection

3) There is little discussion about validation

of PIDs (it is much more about

standardization and very little about control)

Most work has been done in this area.

1) Most referenced work is the 10 Rules for

Persistent URI and Designing URI sets for

UK Public Sector

2) There is no EU agreed policy for PIDs for

centrally managed, shared resources

3) Several guidelines have been put forward

for the URI persistence ( W3C - RFC2616., UK

- Designing URI sets for UK Public Sector,

ISA), but currently these are just

recommendations and not always aligned

Barriers

1) Control and validation are as important as

standardization but often overlooked.
