An interesting article by Warren Harrison from IEEE titled, Whose Information Is It Anyway?, comments on a presentation from ICSE 2003 (the International Conference on Software Engineering) which looked at a software engineering tool that improves the collection of information from email logs, revision control systems, and other development information repositories as aggregated data (XML, etc).
The article acknowledges the advantages of Aggregated Information, but more importantly, identifies the comparison of usefulness and intension when it comes to collecting external data and protecting privacy.
Processes and tools which seemed impossible years ago, are today being discussed in relation to privacy, ethics and copyright, as more and more of these tools are becoming common today.
It is a worthwhile read.
