Webinar: Me4MAP - A method for the development of metadata application profiles

2017-04-21, A metadata application profile (MAP) is a construct that provides a semantic model for enhancing interoperability when publishing data to the Web of Data. When a community of practice agrees to follow a MAP's set of rules for publishing data as Linked Open Data, it makes it possible for such data to be processed automatically by software agents. Therefore, the existence of a method for MAP development is essential to providing developers with a common ground on which to work. The absence of such a method leads to a non-systematic set of MAP development activities that frequently results in ...

Google search now includes schema.org fact check data

Tweet Google claims on their search blog that "Fact Check now available in Google Search and News".

Webinar: Nailing Jello to a Wall: Metrics, Frameworks, & Existing Work for Metadata Assessment

2017-03-24, With the increasing number of repositories, standards and resources we manage for digital libraries, there is a growing need to assess, validate and analyze our metadata - beyond our traditional approaches such as writing XSD or generating CSVs for manual review. Being able to further analyze and determine measures of metadata quality helps us better manage our data and data-driven development, particularly with the shift to Linked Open Data leading many institutions to large-scale migrations. Yet, the semantically-rich metadata desired by many Cultural Heritage Institutions, and the granular expectations of some of our data models, makes performing assessment, much ...
