This document summarizes Gordon Dunsire's presentation on mapping namespaces like FRBR, ISBD, RDA and others to Dublin Core for interoperability. It discusses Dublin Core's origins and intention as a model, the proliferation of richer schemas, and mapping and the sub-property ladder approach. It provides examples of mapping properties from ISBD, RDA, MARC21 and Dublin Core and discusses semantic constraints, reasoning, and interoperability. It also touches on BIBFRAME, schema.org and their roles in relation to Dublin Core mappings.
Last year Declan Fleming presented ALL TEH METADATAS and reviewed our UC San Diego Library Digital Asset Management system and RDF data model. You may be shocked to hear that all that metadata wasn't quite enough to handle increasingly complex digital library and research data in an elegant way. Our ad-hoc, 8-year-old data model has also been added to in inconsistent ways and our librarians and developers have not always been perfectly in sync in understanding how the data model has evolved over time.
In this presentation we'll review our process of locking a team of librarians and developers in a room to figure out a new data model, from domain definition through building and testing an OWL ontology. We¹ll also cover the challenges we ran into, including the review of existing controlled vocabularies and ontologies, or lack thereof, and the decisions made to cover the gaps. Finally, we'll discuss how we engaged the digital library community for feedback and what we have to do next. We all know that Things Fall Apart, this is our attempt at Doing Better This Time.
Piloting Linked Data to Connect Library and Archive Resources to the New Worl...Laura Akerman
Presentation for the CNI (Coalition for Networked Information) Fall Forum, December 2012. Describes Emory University Library’s first-hand experience in interlinking Civil War-related materials and other online resources by leveraging open linked data principles. The library has been actively evaluating linked data’s potential to replace current library processes and services (bibliographic services, finding aids, cataloging, and metadata work) as a more efficient and sustainable means, and one that could bring greater benefit to end users for research and learning. The Library’s initial focus was on workforce education and hands-on learning through real-time experiments: the Connections project was begun to prepare staff to work with linked data, a process that has culminated in a 3-month hands-on pilot to build and convert some data. The pilot introduced the concept to a wide range of staff, including subject liaisons, archivists, metadata librarians, and programmers. Emory’s “silos” of data were interlinked with other open data sources as a way to enhance user discovery and use of library materials on a very limited scale.

The W3C Linked Data Platform (LDP) candidate recommendation defines a standard HTTP-based protocol for read/write Linked
Data. The W3C R2RML recommendation defines a language to map relational databases (RDBs) and RDF. This paper presents morph-LDP, a novel system that combines these two W3C standardization initiatives to expose relational data as read/write Linked Data for LDP-aware applications, whilst allowing legacy applications to continue using their relational databases.

Inovação com Software usando a metodologia Lean StartupsUFPA
Você já percebeu que as grandes inovações e negócios da atualidade, além de um
modelo de negócios inovador, possuem alguma dependência de tecnologias baseadas
em software? São sites, aplicativos e dispositivos que facilitam a busca e compra de
produtos, parceiros, soluções sustentáveis, entre outras inovações. Apesar destas
facilidades, construir software não é uma tarefa simples, tanto do ponto de vista do
empreendedor que encomenda o software quanto para quem vai produzi-lo. Nesta
palestra abordaremos como a metodologia Lean Startup pode ser utilizada para ajudar
a reduzir os riscos de investimentos em produtos que não inovam no mercado e podem
frustrar os empreendedores em seus projetos
Understanding RDF: the Resource Description Framework in Context (1999)Dan Brickley

MR^3: Meta-Model Management based on RDFs Revision ReflectionTakeshi Morita
We propose a tool to manage several sorts of relationships among RDF and RDFS. Our tool consists of three main functions: graphical editing of RDF contents, graphical editing of RDFS contents, and meta-model management facility. Metamodel management facility supports maintenance of relationship between RDF and RDFS contents. The above facilities are implemented based on plug-in system. We provide basic plug-in modules for consistency checking of RDFS classes and properties. The prototyping tool, called MR^3 (Meta-Model Management based on RDFs Revision Reflection), is implemented by Java language. Through the experiment of using MR^3, we show how MR^3 contributes the Semantic Web paradigm from the standpoint of RDFs contents management.
An exploration of a possible pipeline for RDF datasets from Timbuctoo instances to the digital archive EASY.
- Get, verify, ingest archive and disseminate (linked) data and metadata.
- What are the implications for an archive: serving linked data over (longer periods of) time
- Practical stuff.
The International Federation of Library Associations and Institutions (IFLA) is responsible for the development and maintenance of International Standard Bibliographic Description (ISBD), UNIMARC, and the "Functional Requirements" family for bibliographic records (FRBR), authority data (FRAD), and subject authority data (FRSAD). ISBD underpins the MARC family of formats used by libraries world-wide for many millions of catalog records, while FRBR is a relatively new model optimized for users and the digital environment. These metadata models, schemas, and content rules are now being expressed in the Resource Description Framework language for use in the Semantic Web.
This webinar provides a general update on the work being undertaken. It describes the development of an Application Profile for ISBD to specify the sequence, repeatability, and mandatory status of its elements. It discusses issues involved in deriving linked data from legacy catalogue records based on monolithic and multi-part schemas following ISBD and FRBR, such as the duplication which arises from copy cataloging and FRBRization. The webinar provides practical examples of deriving high-quality linked data from the vast numbers of records created by libraries, and demonstrates how a shift of focus from records to linked-data triples can provide more efficient and effective user-centered resource discovery services.
The work of a project to represent UNIMARC in RDF. The current focus is on the UNIMARC Bibliographic format, and the development of an element set for the tags and subfields and of value vocabularies for the coded information block. Discusses issues identified by the project for improving the UNIMARC standard and in its alignment with ISBD and other bibliographic standards such as RDA: resource description and access with examples of linked open data derived from UNIMARC records.

15. How to refine an RDF property [example: Dublin Core]
Triple: Subject Predicate Object
This resource has format Blu-ray Disc
“String”
or
Data: Thing Property

dc:format is a
Range=
Refine: dct:format MediaType

16. Semantic constraints
Property range defines a class for the data triple object
Property domain defines a class for the data triple subject

17. Semantic reasoning: the sub-property ladder
Semantic rule:
If property1 sub-property of property2;
Then data triple: Resource property1 “string”
Implies data triple: Resource property2 “string”

[Not Resource=Manifestation, etc.!]
25. Interoperability
DCMI level 2 of interoperability
Formal semantic interoperability
“based on the shared formal model provided by
RDF, which is used to support Linked Data”
Sub-property ladder and other maps allow data
to be merged at a level of “lowest common
semantic”
Or any higher level
DCMI levels 3 and 4 => Application profiles
Phase 3: Still under construction
Sharing data from local to global applications
26. BIBFRAME
“a high-level model for the library community … within
a much broader context, … well beyond the library
community”
“more than a mere replacement for the library
community's current model/format, MARC. It is the
foundation for the future of bibliographic description”
A bold claim for something which does not mention ICP
(International Cataloguing Principles)
First draft has fewer classes than FRBR
Is this rich enough for library applications?
Can it be a common framework for FRBR/RDA, ISBD, local
schemas, etc.?
27. schema.org
“collection of schemas, i.e., html tags, that
webmasters can use to markup their pages in
ways recognized by major search providers”
very generic data model derived from RDF Schema
“sponsors”: Google, Yahoo, Microsoft Corporation
