Understands trade-offs between “opaque” URIs and URIs using version numbers, server names, dates, application-specific file extensions, query strings or other obsoletable context. – Linked Data for Professional Education https://ld4pe.dublincore.org Learning resources tagged by competency Thu, 19 Nov 2020 14:45:03 +0000 en-US hourly 1 https://wordpress.org/?v=4.9.16 URI design for RDF conversion of CSV-based data https://ld4pe.dublincore.org/learning_resource/uri-design-for-rdf-conversion-of-csv-based-data/ Fri, 18 Aug 2017 08:22:56 +0000 https://ld4pe.dublincore.org/learning_resource/uri-design-for-rdf-conversion-of-csv-based-data/ The sharing of comma-separated files is very common, and a common set of problems arise upon the receipt and processing of data within this format. The RDF vocabulary described in this document provides interpretation instructions to a tool that converts tabular based data into RDF appropriate for linked data publishing. Links to a page which describes a Java-based tool that follows the interpretation vocabulary described here and provides a set of shell script tools to facilitate automatic conversion.

]]> Linking Lives: Creating an End-User Interface Using Linked Data https://ld4pe.dublincore.org/learning_resource/linking-lives-creating-an-end-user-interface-using-linked-data/ Mon, 22 May 2017 07:03:30 +0000 https://ld4pe.dublincore.org/learning_resource/linking-lives-creating-an-end-user-interface-using-linked-data/ This article describes how LOCAH, a JISC-funded project working to make data from the Archives Hub available as Linked Data, continued on in a new form as "Linking Lives". Biographical data is presented on pages which are populated entirely by Linked Data from various authoritative sources (e.g., VIAF, DBpedia). One challenge faced involved data collection via the application' server vs client's web browse. Another was whether to reconcile of multiple source URIs via creation and persistence of a new URI or to map multiple URIs using the "owl:sameAs property".

]]> Designing URI Sets for the UK Public Sector https://ld4pe.dublincore.org/learning_resource/designing-uri-sets-for-the-uk-public-sector/ Tue, 10 Jan 2017 06:45:33 +0000 https://ld4pe.dublincore.org/learning_resource/designing-uri-sets-for-the-uk-public-sector/ This document defines the design considerations and guidance by which UK public sector Universal Resource Identifier (URI) sets should be developed and maintained. They are designed both to encourage those that definitively own reference data to make it available for re-use, and to give those that have data that could be linked, the confidence to re-use a URI set that is not under their direct control.

The intent is to create a ready reference that will be useful for both the beginner and the experienced practitioner alike. It is also intended to grow and mature in line with the practitioner community. NOTE: This is a book-length resource and covers a wide range of different areas from the design of Web-scale identifiers to application development patterns.

It hits all the basic standards and technologies in the Semantic Web stack: the RDF data model, SPARQL, RDF Schema, and OWL- however, none in great depth. However, the focus is placed on how these technologies sit on top of the Web infrastructure which is already in place. HyperText Transport Protocol (HTTP) is discussed in detail.

Part 1 outlines a six-step process for "Publishing Linked Data on the Web". Part 2, "How to Publish Relational Databases as Linked Data", covers the following subjects: Mapping relational databases to RDF; following Linked Data Principles and guidelines; mapping and publication tools; the D2R Server.

]]> Methodological Guidelines for Publishing Government Linked Data https://ld4pe.dublincore.org/learning_resource/methodological-guidelines-for-publishing-government-linked-data/ Wed, 21 Oct 2015 20:15:07 +0000 https://ld4pe.dublincore.org/learning_resource/methodological-guidelines-for-publishing-government-linked-data/ Publishing Linked Data is a process that involves many steps, design decisions and technologies. Some initial guidelines have been provided by Linked Data publishers, but these are still far from covering all the steps that are necessary. This chapter, from the book "Linking Government Data" (Springer, 2011), proposes a set of methodological guidelines for the activities involved in the publication process. These guidelines are the result of the authors' experience in the production of Linked Data in several Governmental contexts and are validated by the GeoLinkedData and AEMETLinkedData use cases.

]]> Relational Database to RDF Translation in the Cultural Heritage Domain https://ld4pe.dublincore.org/learning_resource/relational-database-to-rdf-translation-in-the-cultural-heritage-domain/ Tue, 15 Sep 2015 02:33:10 +0000 https://ld4pe.dublincore.org/learning_resource/relational-database-to-rdf-translation-in-the-cultural-heritage-domain/ The author argues that simple algorithms for automatically mapping relational data to RDF are wasteful and inefficient. Instead, mapping can be significantly improved by using a schema design tailored to RDF, and the smaller graph that results will promote powerful query mechanisms like faceted search. The research reported builds a substantial RDF graph from a real data archive in the cultural heritage domain. Proposed is a generic RDB2RDF mapping for such
data, based on the simple “People, Places, Things and Events” approach
frequently used in heritage data management.
