Vocabulary of Interlinked Datasets

"The Vocabulary of Interlinked Datasets (VoID) is an RDF Schema vocabulary for expressing metadata about RDF datasets. It is intended as a bridge between the publishers and users of RDF data, with applications ranging from data discovery to cataloging and archiving of datasets. This document provides a formal definition of the new RDF classes and properties introduced for VoID."

Data Cube Vocabulary

"There are many situations where it would be useful to be able to publish multi-dimensional data, such as statistics, on the web in such a way that it can be linked to related data sets and concepts. The Data Cube vocabulary provides a means to do this using the W3C RDF (Resource Description Framework) standard. The model underpinning the Data Cube vocabulary is compatible with the cube model that underlies SDMX (Statistical Data and Metadata eXchange), an ISO standard for exchanging and sharing statistical data and metadata among organizations.


"The growing availability of data on the Web provided by Web 2.0 applications and, more recently through Linked Data, brought the computational pattern expressed as ETL to reemerge in a scenario with additional complexity, where the number of data sources and the data heterogeneity that needs to be supported by ETL drastically increases. In this scenario, issues with data quality and trustworthiness may strongly impact the data utility for end-users.

AlgaeBase Taxonomy

"You can browse though the hierarchy by clicking on the names below and drilling down. At each level the numbers of current species are given for each taxon. Only currently accepted names are currently included. Should you find any errors, please click on the little envelope icon, and you can send me an e-mail via the site. In order to make calculations of the numbers of species of living algae, note that 68 or so species of flowering plants (seagrasses) are included for the present (under the Phylum Magnoliophyta), and about 2000 fossil algae, mainly calcium- and silica- secreting forms.
