The term is used most often in relation to [digital media](/source/digital_media), but older forms of metadata are catalogs, dictionaries, and taxonomies. For example, the [Dewey Decimal Classification](/source/Dewey_Decimal_Classification) is a metadata management system developed in 1876 for libraries. ==Metadata schema== Metadata management goes by the end-to-end process and governance framework for creating, controlling, enhancing, attributing, defining and managing a metadata schema, model or other structured aggregation system, either independently or within a repository and the associated supporting processes (often to enable the management of content). For web-based systems, [URL](/source/Uniform_Resource_Locator)s, images, video etc. may be referenced from a triples table of object, attribute and value. ==Scope== With specific [knowledge domain](/source/knowledge_domain)s, the boundaries of the metadata for each must be managed, since a general [ontology](/source/ontology) is not useful to experts in one field whose language is knowledge-domain specific. ==Metadata Manager== In the process of developing a [knowledge management](/source/knowledge_management) solution, creating a metadata schema, and a system in which metadata is managed, a dedicated resource may be appointed to maintain adherence to metadata standards as defined by data owners as well as general [best practice](/source/best_practice). This person is responsible for curation of the business and technical layers of the metadata schema, and commonly involved with strategy and implementation. A metadata manager is not required to master all aspects, or be involved with everything concerning the solution, but an understanding of as much of the process as possible to ensure a relevant schema is developed. ==Metadata management over time== Managing the metadata in a knowledge management solution is an important step in a metadata strategy. It is part of the strategy to make sure that the metadata are complete, current and correct at any given time. Managing a metadata project is also about making sure that users of the system are aware of the possibilities allowed by a well-designed metadata system and how to maximize the benefits of metadata. Regularly monitoring the metadata to ensure that the schema remains relevant is advised. ===Wikipedia metadata=== Wikipedia is a project that actively manages metadata for its articles and files. For example, volunteer editors carefully curate new biographical articles based on the notability (''claim to fame''), name, birth, and/or death dates.See the internal Wikipedia project on the English Wikipedia called Wikipedia:WikiProject Biography Similarly, volunteer editors carefully curate new architectural articles based on name, municipality, or [geo coordinates](/source/geo_coordinates).See Wikipedia:WikiProject Architecture When new articles with a valid alternate spelling are added to Wikipedia that match up to existing articles based on metadata, these are then manually checked and if needed, tagged for merging.See Wikipedia:WikiProject Merge When new articles are added that are considered out of scope or otherwise unfit for Wikipedia, these are nominated for deletion.See Wikipedia:Articles for deletion To help keep track of metadata on Wikipedia, the new Wikimedia project [Wikidata](/source/Wikidata) was established in 2012.

File:Article catedral pantalla estreta.png|This screenprint of the [Catalan Wikipedia](/source/Catalan_Wikipedia) page on the cathedral features several photos including this one. The screenprint was uploaded to Wikimedia Commons in 2007 soon after the photo was available there, but [that article](/source/%3Aca%3ACatedral_de_Barcelona) on the Catalan Wikipedia has since been expanded. == See also == * {{anl|Data defined storage}} * {{anl|Metadata discovery}} * {{anl|Metadata publishing}} * {{anl|Metadata registry}} * {{anl|ISO/IEC 11179}} * {{anl|Dublin core}} ==References== {{reflist}} {{DEFAULTSORT:Meta-Data Management}} Category:Metadata Category:Data management --- Adapted from the Wikipedia article [Metadata management](https://en.wikipedia.org/wiki/Metadata_management) by Wikipedia contributors ([contributor history](https://en.wikipedia.org/wiki/Metadata_management?action=history)).
