Power to the people!Introducing Open Linked Data services to the national legal

database of the Library of the National Congress of Chile

Legislation

Legislation is public information…

… and must be of public domain

Legislation

Juridical certainty

certitude of the content of the legal norm

Legislation

50’scard based compilation of references of links between norms and classified them by subject

Legislation

80´sthe card system was replaced by an automated STAIRS based system

midst 90’sthe system was replaced by a client-server BASIS PLUS architecture, which could reconstruct online the whole texts of the norms

Modeling the “life” of a legal norm

LeyChile

Modeling the “structure” of a legal norm

LeyChile

XMLText: versions, hyperlinks, references, notes

Structure: Hierarchical organization of the parts of a norm

Metadata: additional information of the formal document, such as identification of the norm, subjects, free retrieval terms, etc.

LeyChile: our offer to humans

LeyChile: our offer to machines

LeyChile: is it possible to incorporate linked-open data (LOD)?

Natural extension

Improve interoperability (more formats)

Create domain ontologíes

Offer a solution to complex queries using a SPARQL endpoint

First step: expose metadata of the norms

LOD principles: URIs

Careful design (acts, laws, decrees, rules, resolutions…)

First step finished in may 2011More than 300.000 norms exported≈27 triples by norm≈8 million triples

200 to 400 triples added each day

Actual and future work

More datasets at the endpoint: biographies, transparency, geographical data, history of the law, legislative documents…

Expose parts of a legal norm and their metadata

Visualizations

Complex queries made easy

Findings

Open data, open linked data, semantic web is more than a technology… it is a way of managing information

Visualization is not a final product, is a feedback process of data “ablution” and improving the visualization

Creates value for ourselves 1

Many technical details and challenges remain unsolved 1
