PIM frameworks

Deborah Barreau

To understand how PIM is performed, Deborah Barreau tried to dismember it and so divided it in 5 sub- activities:

• Acquisition: deciding which information will be included in information space, defining, la- belling and grouping information.
• Organization and Storage: classifying, naming, grouping and placing information for later retrieval.
• Maintenance: updating out-of-date information, backing up information, moving or deleting information from information space.
• Retrieval: process of finding information for reuse and • Output: visualizing the information space based on users’ needs and objectives.

PIM activities and activities outside PIM by Richard Boardman

Barreau's classification of PIM activities was a basis for Richard Boardman’s classification. Boardman argued that updating information content cannot be a part of PIM, as it deals with content of information items. He also argued that visualizing is done by computers (not users) and that visualization is present in all sub-activities. He describes four PIM sub-activities as:

• Acquisition: naming and/or (deciding of a) placement in information space.
• Organization: placing information items, renaming, moving and creating new folders.
• Maintenance: backing up and deleting information from information space.
• Retrieval: browsing, sorting and searching for information.
