IDOL OnDemand by HP offers an array of data processing APIs for format conversion, image analysis, indexing, search, and textual analysis. Preview capabilities exist to view how many of these RESTful APIs behave in action. Their set of Indexing APIs allow for general databasing functionalities. Indexes come in different formats called "flavors" which vary according to maximum number of documents, scaling performance, and number of field types. The List Index API returns a list of the names of all dynamic data sets that have been created with the Create Text Index API.
