Metadato Metadatos (del griego μετα, meta, 'después de, más allá de'[1] y latín datum, 'lo que se da', «dato»[2] ), literalmente «sobre datos», son datos que describen otros datos. En general, un grupo de metadatos se refiere a un grupo de datos, llamado recurso. El concepto de metadatos es análogo al uso de índices para localizar objetos en vez de datos. Por ejemplo, en una biblioteca se usan fichas que especifican autores, títulos, casas editoriales y lugares para buscar libros. Así, los metadatos ayudan a ubicar datos.[3] Definiciones[editar] El término «metadatos» no tiene una definición única. Podemos también considerar los metadatos, en las áreas de telecomunicaciones e informática, como información no relevante para el usuario final pero sí de suma importancia para el sistema que maneja la data. En el campo biológico los metadatos se han convertido en una herramienta fundamental para el descubrimiento de datos e información.

RDF Overview RDF is a standard model for data interchange on the Web. RDF has features that facilitate data merging even if the underlying schemas differ, and it specifically supports the evolution of schemas over time without requiring all the data consumers to be changed. RDF extends the linking structure of the Web to use URIs to name the relationship between things as well as the two ends of the link (this is usually referred to as a “triple”). Using this simple model, it allows structured and semi-structured data to be mixed, exposed, and shared across different applications. This linking structure forms a directed, labeled graph, where the edges represent the named link between two resources, represented by the graph nodes. Recommended Reading The RDF 1.1 specification consists of a suite of W3C Recommendations and Working Group Notes, published in 2014. A number of textbooks have been published on RDF and on Semantic Web in general. Discussions on a possible next version of RDF

Conference on Bibliographic Control in the New Millenium Celebrating Cataloguing in the 20th Century a talk given at the Library of Congress Bicentennial Conference on Bibliographic Controlfor the New Millennium Washington, D.C., November 15th 2000 Michael Gorman Dean of Library Services California State University, Fresno Final version I dreamed I saw Joe Hill last night, Alive as you or me: Said I, but Joe you're ten years dead; I never died said he. I never died said he. And standing there as big as life A-smiling with his eyes. Said Joe, what they forgot to kill Went on to organize, Went on to organize.The Ballad of Joe Hill by Alfred Hayes and Earl Robinson (1925) Introduction The story of cataloguing in the 20th century is the story of two structures. What, fundamentally, is the topic of this conference? Just as in the early 1900s, there is a tendency today to belittle the importance of descriptive cataloguing, even by people, who should know better (I shall deal with them later.)

Data is out of beta Starting today, Mendeley Data is out of beta. We’re extremely happy with all the great datasets people have been submitting, and we now think that the product has reached the level of maturity where it has all the features people need to publish their research data online. If you haven’t heard of Mendeley Data before, it’s a new product that allows anyone who has data from experiments to publish it online and get a DOI for it so that it is citable. Some of the new things we’ve introduced over the last few months are an expanded category selection (we now have over 4,000 categories to choose from!) We like to make sure that our service is available 24/7, so that you can use it day or night. We’ve got some exciting new features around the corner, the biggest of which is a new search functionality that will make it easier then ever to find datasets which you are interested in. So what are you waiting for? Like this: Like Loading...

Semantic Web Standards Dublin Core Dublin Core es un modelo de metadatos elaborado y auspiciado por la DCMI (Dublin Core Metadata Initiative), una organización dedicada a fomentar la adopción extensa de los estándares interoperables de los metadatos y a promover el desarrollo de los vocabularios especializados de metadatos para describir recursos para permitir sistemas más inteligentes el descubrimiento del recurso. Las implementaciones de Dublin Core usan generalmente XML y se basan en el Resource Description Framework. Dublin Core se define por ISO en su norma ISO 15836 del año 2003, y la norma NISO Z39.85-2007. Descripción general[editar] Dublin Core es un sistema de 15 definiciones semánticas descriptivas que pretenden transmitir un significado semántico a las mismas. Estas definiciones: Son opcionalesSe pueden repetirPueden aparecer en cualquier orden Clasificación y elementos[editar] En general, podemos clasificar estos elementos en tres grupos que indican la clase o el ámbito de la información que se guarda en ellos:

TEI: Text Encoding Initiative The Catalog as Portal to the Internet Final version December 2000 "I don't do libraries," stated an engineering student last year at an Ivy League university, pleading with his professor to absolve him from an assignment requiring him to seek information in the campus library, presumably necessitating use of the library catalog. Increasingly, even at leading institutions of higher education, one encounters not just students, but also faculty and deans who assert that they get all the information they need through the Internet. Q. Arms then provides anecdotal evidence of a colleague who meets 80% of his information needs through open source documents. Libraries are awash in contradictions. With the addition of digital materials to the library's portfolio a debate about the role of the catalog has also developed. This paper examines the potential of the catalog to serve as a portal to the Internet. We have just begun in America, an era of huge libraries, The average size is increasing very fast.
