1. Why do we need Linked Data? - quiz

Which of the following statements are true (multiple options):

Datafication is the process of replacing textual information by structured data
The structure of an ontology is determined by the system requirements of the system that generates the data
A zettabyte is the last byte in a dataset, marking the end of the file
The problem of data integration is that the meaning of the data is implicit, so that manual labor is needed to translate the data to some common language
Traditional datasets are difficult to integrate because they are interpreted without paying attention to what the data mean
Creating effective ontologies is an art and a matter of taste

Linked Data is:

An approach to publish and interconnect data on the web in a way that makes them easier to integrate
An approach to express, use and exchange data in a way that preserves the meaning of these data, using the open standards of the web
A W3C web standard defining the technical language in which data is expressed in a way that makes interconnecting data easier

Which of the following statements are true (multiple options):

An true ontology is expressed in RDF, not UML
A conceptualization is a nugget of shared interpretation
The problem of false agreement arises when the user of a dataset violates the rules set by the provider
False Agreement arises when datasets use different terms for the same things
Datasets make statements about the world
A CSV-file is interpreted using an ontology, even if the ontology is left implicit

RDF and FAIR try to make data more interoperable. Ultimately, this requires:

That data providers agree on a common approach to format data
That data are made available on the web
That the meaning of data is explicitly described
That application software is programmed so that it interprets data correctly in all circumstances

Which statement expresses the ambition of the FAIR movement most accurately? Our society needs:

A new approach to make digital resources easier to use by increasing the amount and quality of metadata
A new approach to make digital resources easier to use by increasing the amount and quality of metadata and requiring them to be made available publicly
A new approach to make it possible to make more scientific discoveries against less cost by reusing data
A new social contract, supported by legal and technological infrastructure, to make digital resources available in a responsible manner
A new social contract, supported by widely used community standards, to make digital resources findable, accessible, interoperable and reusable

Which of the following statements are true (multiple options):

Enabling machines to understand data accelerates scientific discovery
FAIR data offers a new way of federating data across data providers
Value generation through FAIR data will mostly just impact academia
FAIR is formulated in terms of detailed specifications
Shared, high-quality ontologies play a central role in FAIR Data
Linked Data is the obvious and natural way to implement FAIR Data, but not the only way
FAIR is a political initiative of the European Commission that was adopted by the G20

Which of the following statements are part of the Data-Centric Manifesto (multiple options):

Data is a key asset of any person, organization, and society
Data is self-describing and does not rely on an application for interpretation and meaning
All data in the enterprise is stored in a single, centralized database
Access to and security of the data is managed by applications
Applications are allowed to visit the data, perform their magic and express the results of their process back into the data layer
