Datos 1.0 (2011)

Publish data according to IFLA models and vocabularies: FRBR, ISBD

PRIMARY GOAL:

CONTENT:

2.4 millions bib records (ancient and modern monographs, printed music and sound recordings) and authority records

AVAILABILITY:

Datadumps and Sparql end-point access

TARGET AUDIENCE:

Developers, LOD experts, data consumers


Datos 2.0 (2014) PRIMARY GOAL:

CONTENT:

AVAILABILITY:

Human interface, Sparql end-point access and other services

Build an innovative gateway to collections, profiting from Linked Data technology and FRBR model

Almost all the catalogue (except serials and items), access to digital objects

TARGET AUDIENCE:

Common users, researchers, reference librarians


Datos 2.0 (2014) MAIN FEATURES:

Allow users to experiment with new ways of discovering resources Covering nearly all the resources in the library Access to digitized content Data enriched and linked to outside sources FRBR as a model of reference Resources to be discovered and accessed straight from Google Resources described with BNE ontology


Datos 2.0: front-end A BRAND NEW CATALOGUE!!!

MULTI-DEVICE RESPONSIVE!!!

ENTITY-DRIVEN SEARCH!!!

FULLY ENRICHED AND LINKED!!!

FRBR-BASED SEARCH RESULTS RANKING!!!

datos.bne.es: the making-of MARC21 data extracted

and analyzed Mapping 1: assigning data

to WEM entities

Mapping 2: relating entities

Mapping 3: Properties’ annotation

Publication pipeline


DATOS 1.0

Struggling with FRBR

Data that could not be linked was ignored Solid data model, but huge data loss

Struggling with FRBR

No data loss, but FRBR loopholes The “missing works” affair

Expressions as mere facets?

Data (Marc)

Data analysis Mapping & sorting

Linked Data generation

Data generation

Publication pipeline

Indexing

Double storing Front-end Triple store

Ranking based in FRBR relationships

No data transformation made after generation Schema.org annotations in every entity html page

Post processing Linking

Enrichment


Other [LOD] services

SPARQL end-point Search API Content negotiation In development: Extended API Dumps


Outcomes datos.bne.es as:

Source for data consuming applications Intermediate source of data

Expert users

Reference tool Integrating device Librarians

New ways to access and discover resources Access from search engine results

Common users


Internet exposure People coming straight from search engine results

Specially in the “long tail” resources


Internet exposure : contents

- Hidden resources made visible. (You got

pictures of my town!!, That’s the weird out-of-print issue I’ve been looking for!!)

- Errors warning

- Misconceptions about services (I want to buy

/ download this item !!!) - False expectations.


Internet exposure : people

- Hey¡ That’s me on the Internet!. Do you want more data? Do you want more of my books? - I know that author!!!. Do you want more data?

- Hey¡ That’s me on the Internet!. And I don’t want to be on the Internet!!!!


FRBR for users

Useful for:

- Grouping related things - As a general model for stablishing relationships

Lessons learned: - Use FRBR, don’t talk FRBR. - Simple relationships are harder to explain.
