 A dataset is an identifiable collection of structured data objects unified by some criteria (authorship, subject, scope, spatial, or temporal extent...). A catalog is a collection of descriptions of datasets; each description is a metadata record. The intention of a data catalog is to facilitate data access by users who are first interested in a particular kind of data, and upon finding a fit-for-purpose dataset, will next want to know how to get the data.
 
-A Web API (**A**pplication **P**rogramming **I**nterface) allows computer programs to dynamically query a dataset using the World Wide Web. For example, a dataset [of farmers markets](https://explore.data.gov/Agriculture/Farmers-Markets-Geographic-Data/wfna-38ey) may be made available for download as a single file (e.g. a CSV), or may be made available to developers through a Web API, such that a computer program could use a ZIP Code to retrieve a list of farmers markets in the ZIP Code area.

 The catalog file for each agency should list all of the agency's datasets that can be made public, regardless of whether they are distributed by a file download or through a Web API.  The **Endpoint** data element is used to indicate which datasets offer Web APIs (see below for more information on Common Core and Extended metadata elements).
