Extensible data transformations

A computer-implemented method for facilitating data transformations, the method comprising:

• receiving a new transformation tool from an enterprise user of a transformation service prior to storing the new transformation tool in a repository;
• generating annotations and storing the annotations in association with the new transformation tool in the repository, wherein one of the annotations includes a security level annotation;
• receiving a set of example values;
• determining that the security level associated with the new transformation tool permits the new transformation tool to be used to transform data associated with the set of example values;
• and
• using the new transformation tool to transform data associated with the set of example values.

One or more computer storage media having computer-executable instructions embodied thereon that, when executed by one or more processors, cause the one or more processors to perform a method for facilitating data transformations, the method comprising:

• receiving a new transformation tool from a user of a transformation service, wherein the new transformation tool comprises a transformation tool prior to being identified as relevant to a first data transformation;
• automatically generating annotations for the new transformation tool;
• storing the annotations and the new transformation tool in a repository having a plurality of transformation tools;
• receiving a set of example values associated with the first data transformation;
• based on receiving the set of example values, search the repository to identify the new transformation tool as relevant to the first data transformation associated with the received set of example values;
• use the new transformation tool to generate a transformation program that produces transformed output values;
• and
• generate additional annotations for the new transformation tool based on the transformed output values.
