Una Mirada a la Web de los Datos. Caso de Estudio: Consumo de Servicios CKAN

Abstract

Context: In order to assess basic criteria so as to obtain preliminary guidelines on the current state of the Web of Data, we analyze the connection and use of the services offered by CKAN - Comprehensive Knowledge Archive Network; the analysis is conducted through exploration and connection to datasets published in the datahub.io open data repository.Method: We use the services offered by CKAN for browsing and downloading datasets published in Datahub.io, we propose a procedure carried out to analyze the downloaded data. The proposal consists of three key activities: (1) review and analysis of platform, (2) Setting up and using the services provided by the API and (3) download and review of the information obtained.Results: The required services offered by the platform CKAN were configured and deployed, in order to carry out queries and downloads related to each dataset. The obtained information was processed and analyzed from the downloaded JSON, allowing a comparative preliminary analysis of the information regarding the behavior of the Web of Data.Conclusions: CKAN is a powerful tool to manage data catalogs. This tool can handle a description of the data and other relevant information, from organizations that publish to people who query such information. These queries provide information as categories of organizations, data formats and owners, the type of publication licenses, links to other data, among other which are relevant to perform an analysis of the Web data.

“…Cuando se realizan búsquedas en la plataforma CKAN se pueden desplegar un listado de conjunto de datos específicos, que pueden contener dos elementos (CKAN, n.d.-b;Herrera-Cubides, Gaona-García, & Gordillo Orjuela, 2017), que son: Los metadatos. -proporcionan información como el título, descripción, etiquetas, licencia, propietario, fechas, entre otros.…”

The Relevance of Open Data Principles for the Web of Data

“…Regarding the state of the Web of Data, diferent studies [4,7,[29][30][31][32][33][34][35][36] and [37] expose several issues regarding requirements to reach all linked data levels. Te low use of machine-readable formats, the lack of adequate open licensing terms which do not impede its reuse for free, metadata with little human readability, out-of-date data, the extra efort required to get the fve stars of the linked data model, and the under reuse and enrichment of data briefy summarize their main fndings on these researches.…”

Abstraction of linked data’s world

“…Data management platforms define a set of rules for HTTP operations on web resources, based on RDF. They also provide an architecture and some type of exploitation interface, either for interaction with humans or with other software systems, [41,42]. Within identified platforms are a) Repositories, which store resources and metadata, b) Referatory, in which metadata is managed and a link to resource, and c) Federations, which correspond to groupings of repositories with a common access point, such as: Ariadne, Globe, among others, [43].…”
