 Standard Metadata Vocabulary
 ----------------------------
-Metadata is structured information that describes, explains, locates, or otherwise makes it easier to retrieve, use, or manage an information resource (NISO 2004, ISBN: 1-880124-62-9).  The challenge is to define and name standard metadata fields so that a data consumer has sufficient information to process and understand the described data. The more information that can be conveyed in a standardized regular format, the more valuable data becomes. Metadata can range from basic to advanced, from allowing one to discover the mere fact that a certain data asset exists and is about a general subject all the way to providing detailed information documenting the structure, processing history, quality, relationships, and other properties of a dataset. Making metadata machine readable greatly increases its utility, but requires more detailed standardization, defining not only field names, but how information is encoded in the metadata fields.

 Establishing a common vocabulary is the key to communication. The **metadata schema** specified in this memorandum is based on [DCAT](http://www.w3.org/TR/vocab-dcat/), a hierarchical vocabulary specific to datasets. This specification defines three types of metadata elements: Required, Required-if (conditionally required), and Expanded fields.  These elements were selected to represent information that is most often looked for on the web. To assist users of other metadata standards, [mappings](http://project-open-data.github.io/metadata-resources/#common_core_required_fields_equivalents) to equivalent elements in other standards are provided.
