How RDF Can Use MARC in the Semantic Web World

Just like current library materials are accordingly categorized, in many ways, Resource Description and Framework does the same with Web, as it is about representing metadata about Web resources, such as the title, author, and modification date of a Web page, copyright and licensing information about a Web document, or the availability schedule for some shared resource.RDF As Abstract Web However, going one step further, RDF can also be used to represent information about abstract concepts (such as user preferences, prices, and availability of online items) that cannot be directly retrieved on the Web.Because RDF can be used for situations in which this information needs to be processed by applications, rather than being only displayed to people, RDF is a powerful Web tool for knowledge representation and organization, as RDF provides a common framework for expressing this information so it can be exchanged between applications without loss of meaning.RDF and XML In Solving the Semantic WebIn many ways, RDF is key to the SemWeb, for it permits for the coalition and interchange of Web data and standards, one which uses XML to solve a two-dimension relational database world cannot. RDF provides a global and persistent way to link data together.RDF isn't a programming language, but a method (think of it as a - HTTP://RAPIDSERVICESGROUP.COM/ - container) for grouping the currently unorganized mess of data on the Web, while ultimately tiling the way for - HTTP://RAPIDSERVICESGROUP.COM - a sinuous exchange of different standards on the Web.De-Siloization of the Semantic WebThink of the current Web as separate pockets or databases of information, much of it hidden behind the doors of proprietors and organizations. In employing and embedding the rich potential of RDF in Web pages (and products), the Web moves one step closer to the realization of stitching the Web into one large global database.Think of the next generation Web where people or a machine could start off in one database, and then move through an unending set of databases which are connected not by wires but by being about the same thing.RDF Triples and Three-Dimensional Representation - RAPIDSERVICESGROUP.COM/ - of Knowledge and Data on the WebInstead of restricting Web data in relational database cubes or tables, RDF allows for liquid interchange of metadata of the Web. Structured and represented as triples, that is subject-predicate-object combinations that provide for a multidimensional representation and linking of the Web, RDF connects disparate pieces of data and nodes in an otherwise unrelated silo of networks.Library MARC RecordsThis is not unlike what LIS professionals have been doing for decades when automation required the use of MARC records for transactions between electronic calatogue records. Known as MA chine-ReadableCataloging records, MARC records contain a guide to its data, or little "signposts," before each piece of bibliographic information.Just like RDF Triples of noun-predicate-object, MARC 21 interestingly MARC records are composed of three elements: the record structure, the content designation, and the data content of the record.With computer catalogues, MARC not only allows for libraries to better share bibliographic resources through standardization, it also thwarted - - duplication of cataloging work and ultimately enabling libraries to acquire cataloginguing data that is predictable and reliable.Not only did MARC enable libraries to make use of commercially available library automation systems to manage library operations, it allowed libraries to replace one integrated library system (ILS) with another with the guarantee that their data will still be compatible after migration of data. This not only prevented data siloization, it allowed for consortia among libraries - - across different countries.Standardization of MARCHowever, for MARC 21 to have - - worked, it needed complete cooperation among the different libraries of the World. In the 1960s, the Library of Congress in the United States becamse as the official depository of United States publications and is a primary source of cataloging records for US and international publications.The original American version of MARC became known as USMARC in the 1980s; there was also a separate Canadian version with minor differences called CAN/MARC. After making minor changes to both formats, the USMARC and CAN/MARC specifications were merged in 1997 to create MARC 21.Standardization of the Semantic WebAlthough countries use their own MARC system (e.g. Denmark using danMARC2 or Australia - - using AUSMARC), MARC provides the protocol by which computers exchange, use, and interpret bibliographic information by linking data elements up to form the foundation of most library catalogs used today. The Semantic Web in many ways will be based on using this type of linking up of data, but perhaps on a much larger, global, and uniform catalog and database.
