Data feed having customizable analytic and visual behavior

A computer-readable memory device storing computer-executable instructions for execution on a computer processor that, in execution, carry out a method comprising:

• providing a plurality of data feeds, each of the plurality of data feeds being associated with one of a plurality of domains of interest, wherein each of the plurality of data feeds is individually accessible by a third-party, and wherein access to any of the plurality of data feeds is conditioned upon a third-partys purchase of access to the data feed;
• providing a plurality of customizable preview applications, wherein each of the plurality of preview applications comprises sample data, business logic, and one or more user interfaces for an associated data feed of the plurality of data feeds, and provides a preview of sample data specific to the associated one data feed, and wherein each preview application comprises a plurality of expressions specifically directed to operate on data of the associated data feed, each expression comprising a symbolic representation of a computation to be performed;
• receiving a discovery request from a third-party, the discovery request specifying a domain of interest of the plurality of domains of interest;
• identifying a set of data feeds of the plurality of data feeds corresponding to the specified domain of interest of the discovery request;
• providing selection information regarding the identified set of data feeds to the third-party in response to the discovery request;
• receiving, from the third-party, a selection of a data feed of interest, the selected data feed of interest being one of the identified set of data feeds;
• and
• in response to the third-party's selection of the selected data feed, providing a preview application associated with the selected data feed and sample data representative of the selected data feed of interest to the third-party.

A computing system comprising one or more processors coupled to one or more memories, wherein the one or more processors execute instructions stored in the one or more memories as part of or in conjunction with additional components to cause the one or more processors to:

• provide a plurality of data feeds, each of the plurality of data feeds being associated with one of a plurality of domains of interest, wherein each of the plurality of data feeds is individually accessible by a third-party, and wherein access to any of the plurality of data feeds is conditioned upon a third-party's purchase of access to the data feed;
• provide a plurality of customizable preview applications, wherein each of the plurality of preview applications comprises sample data, business logic, and one or more user interfaces for an associated data feed of the plurality of data feeds, and provides a preview of sample data specific to the associated one data feed, and wherein each preview application comprises a plurality of expressions specifically directed to operate on data of the associated data feed, each expression comprising a symbolic representation of a computation to be performed;
• receive a discovery request from a third-party, the discovery request specifying a domain of interest of the plurality of domains of interest;
• identify a set of data feeds of the plurality of data feeds corresponding to the specified domain of interest of the discovery request;
• provide selection information regarding the identified set of data feeds to the third-party in response to the discovery request;
• receive, from the third-party, a selection of a data feed of interest, the selected data feed of interest being one of the identified set of data feeds;
• and
• in response to receiving a selection of a data feed from the requester, transmit to the third-party a preview application specifically configured to interact with the selected data feed.
