Abstract: Improvements for parametized storage and retrieval of multiple different types of marketplace items include: (a) providing lists recommended parameters to guide users' entry and searching of data; (b) limiting users to suggesting additions of new parameters to the system; (c) an item classification based in whole or in part upon a trademark classification; (d) a data structure in which value data is stored in cells of a table for which a given column can represent multiple different parameters; (e) values can comprise links that resolve to particular items of data other than a file, a web site, and an email address; data is loaded en masse, and then distributed to edge cache databases; and (f) users can privatize individual records and values within their loaded data.

Abstract: Computer implemented systems store descriptions of multiple different types of marketplace items as a collection of parameter-value pairs, using a table having a plurality of rows and columns, wherein values for at least two of the items are stored in cells of first and second ones of the rows, respectively; keys that provide information that can be used to decipher differential mappings of a plurality of the columns to a plurality of parameters in different ones of the rows; and one or more interfaces that collectively display previously stored parameters and values to a human end-user.
