Validating RDF Data

Fri, 15 Sep 2017 09:45:50 +0000

This book describes two languages for implementing constraints on RDF data, describing the main features of both Shape Expressions (ShEx) and Shapes Constraints Language (SHACL) from a user perspective, and also offering a comparison of the technologies. The authors develop a small number of examples that typify validation requirements and demonstrate how they can be met with ShEx and SHACL. The book is not intended to be a formal specification of the languages, for which the interested reader can consult the corresponding reference documents, but rather, it is meant to serve as an introduction to the technologies with some background about the rationale of their design and some points of comparison.

Open Refine 101

Fri, 25 Aug 2017 08:34:44 +0000

This free online course explains that while data cleaning, preparation and enrichment take up an enormous amount of time, and is nevertheless a crucial stage in the data science methodology. However, data transformation tools haven’t fully caught up with the popularity of data analysis. Learn why domain experts need powerful yet easy-to-use interfaces to explore new data sets, normalize them and process them via innovative services often available via an API only. The instructor demonstrates the strengths of OpenRefine, which are that it offers a self-service agile and iterative interface for data discovery and preparation, as well as an easy-to-learn scripting language.

Using the Convert CSV to RDF ingest tool

Fri, 18 Aug 2017 08:22:56 +0000

This guide will walk through the use of the Convert CSV to RDF tool, a semi-automated method of converting comma separated or tab separated text files into RDF that can be displayed in VIVO. These files should include one row of data per record (e.g., a person or publication) and represent the fields or properties associated with each record in separate columns within the row, much as the values appear in a spreadsheet. The most common pattern of loading CSV files involves one CSV file per type of data to be loaded. Note, the current ingest tools involve working through a number of steps from original source data files to the appearance of new data in VIVO. The process requires some understanding of semantic web data modeling and some training.

Linked Data for Libraries, Archives and Museums: How to clean, link and publish your metadata

Mon, 22 May 2017 07:03:30 +0000

This handbook teaches how to unlock the value of existing metadata through cleaning, reconciliation, enrichment and linking, as well as how to streamline the process of new metadata creation. It introduces the key concepts related to metadata standards and Linked Data and how they can be practically applied to existing metadata. Chapters are dedicated to modeling, cleaning, reconciling, enriching, and publishing one's data.

The Semantic Web and Linked Data Concepts: The RDF Data Model and Linked Open Data (LOD)

Fri, 19 May 2017 07:03:10 +0000

This PowerPoint presentation was used during the "Introduction to the Semantic Web and Linked Data" module of the pilot training project developed by the Library of Congress which tested the use of BIBFRAME for bibliographic description. This presentation explains the RDF data model, the use of URIs to identify resources, and other RDF "tools". BIBFRAME is discussed as one of many vocabularies and ontologies being used to describe relationships between resources on the Semantic Web. The wider concept of Linked Open Data (LOD) is introduced along the principles and practices that support it. The module's home page contains links to more materials.
