Data Catalog Vocabulary DCAT

Posted by & filed under .

DCAT is an RDF vocabulary designed to facilitate interoperability between data catalogs published on the Web. This document defines the schema and provides examples for its use. By using DCAT to describe datasets in data catalogs, publishers increase discoverability and enable applications easily to consume metadata from multiple catalogs. It further enables decentralized publishing of… Read more »

Digital Object Architecture

Posted by & filed under .

The Digital Object Architecture provides a mechanism for the creation of, and access to, digital objects as discrete data structures with unique, resolvable identifiers. These Digital Objects provide a foundation for representing and interacting with information on the Internet. From CNRI’s Press Release: With the software suite, organizations can provide an interoperable interface to individually… Read more »

taverna-prov: Taverna Workflow Engine Prov Export

Posted by & filed under .

Taverna-prov is a plugin for the Taverna Workbench and Taverna Command Line – a scientific workflow engine. The plugin allows the export of the provenance of a workflow run according to the W3C PROV-O standard. The provenance is exported as a .bundle.zip file  which species a structured ZIP file with a manifest (.ro/manifest.json) that corresponds to the RO bundle specification. The following… Read more »

myExperiment.org

Posted by & filed under .

myExperiment provides an early example of the use of Research Objects through the use of “packs”. myExperiment packs are represented using OAI-ORE and available as linked data and hence semantically-described for ease of discovery and reuse. They typically contain computational workflows, although this is not essential – the bundles are useful anyway, and this is… Read more »

OKF Data Packages

A Data Package (or DataPackage) is a simple way of “packaging” up data. To create a Data Package, all you need to do is place a “descriptor” file named datapackage.json in the top-level directory of your set of data files. Why Data Packages? How Can They Help? Imagine a situation such as the following: You have a… Read more »

Clinicalcodes.org Exchange

Posted by & filed under .

The clinicalcodes.org repository holds code lists for published electronic medical record studies (i.e. the coded descriptions of study cohorts). The goal of clinicalcodes.org is support replication of previously published studies. Using the Research Object model, an export of a study packages codes, study, and metadata together to support exchange. An Example RO exported in this manner… Read more »

RO Bundle (Zip)

Posted by & filed under .

The RO Bundle specification defines a file format for storage and distribution of Research Objects as a ZIP archive; called a Research Object Bundle (RO Bundle). RO Bundles allow capturing a Research Object to a single file or byte-stream by including its manifest, annotations and some or all of its aggregated resources for the purposes of exporting, archiving, publishing and… Read more »

Nanopublications

Nano publications provides a model and vocabulary for describing a scientific statement – along with the context for that statement – in a machine readable manner.   From nanopub.org: A publication is the smallest unit of publishable information: an assertion about anything that can be uniquely identified and attributed to its author. Individual nanopublications can… Read more »

Research Object (RO) Model

Posted by & filed under .

RO Model Core The core concepts of research objects, identity, aggregation, and annotation, are captured in the specification of the ro model. The specification of this core research object model is described in the ro ontology under the namespace http://purl.org/wf4ever/ro#. Extensions There are also the following ontology implementations of extensions to the core research object model: The roevo model… Read more »
