The Registry Interchange Format - Collections and Services (RIF-CS) is an XML vocabulary for representing metadata about data collections and related entities based on ISO 2146.〔Global Registries, ("The Registry Interchange Format - Collections and Services (RIF-CS)" ), Retrieved on 4 January 2013.〕 It is a machine-readable format to describe metadata about data collections. Similar to how MARC standards are used by library systems to describe books, RIF-CS is used to describe data collections. For example, a RIF-CS record can describe a spreadsheet containing experimental results: it might contain the title, description, creator, keywords, date the experiment was conducted and a URL to obtain the actual spreadsheet. Another RIF-CS record can describe the person who created the spreadsheet: it might contain their name, address and contact email. RIF-CS documents, containing RIF-CS records, are exchanged between computer systems. For example, a university can send the RIF-CS documents to a national database, where it can be indexed and searched. People can download RIF-CS records from a national database to use the information to find out more about the data and/or the researcher. == Model == The metadata describes the entity as well relationships between the entities. RIF-CS represents metadata about the following types of entities, which it calls ''registry objects'':〔Australian National Data Service, ("Learn about RIF-CS" ), Retrieved on 4 January 2013.〕 * Collections * Parties * Activities * Services These entities are based on the entities defined in ISO 2146.〔ISO, ("ISO 2146:2010 Information and documentation - Registry services for libraries and related organizations" ).〕 The ''registry objects'' contain either embedded information or links to other ''registry objects''. Some information is represented directly in the ''registry object''; for example: names, descriptions and dates. Other information is represented by a link to another ''registry object'': for example, the creator for a collection (research data) is a link to another ''registry object'' that describes the party (a researcher). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「RIF-CS」の詳細全文を読む スポンサード リンク
