User-specified user application data sharing

A system, comprising:

• a memory;
• and
• a processor programmed to, by an operating system of a first computing device used by a user:
• receive an indication initiated by the user within a first local user application that specifies existing user-selected configured sharable data configured as part of a data set within the first local user application as sharable by the first local user application with different user applications, where the different user applications perform different application-level tasks that identify new information of relevance to the user according to data content of the configured sharable data;
• determine whether any other different user applications share data compatibility with at least one portion of the configured sharable data, where the processor is programmed to:
• identify data configured as sharable within each of a plurality of other different user applications executable by the operating system that is compatible with the configured sharable data;
• filter the identified data configured as sharable of each of the plurality of other different user applications using the configured sharable data;
• and
• identify a first subset of compatible data within the configured sharable data as the at least one portion of the configured sharable data;
• where the processor is further programmed to:
• configure, within the memory in response to determining that at least one other different user application shares the data compatibility with the at least one portion of the configured sharable data, a data share indication to the at least one other different user application that causes the at least one other different user application to perform a requested application-level task using the configured sharable data;
• and
• obtain at least one new item of information on behalf of the user from the at least one other different user application in response to the requested application-level task performed using the configured sharable data.
