IBM’s effort to make its Notes/Domino platform relevant for the future kicks up a gear this week, as the company prepares a second beta of a new version 10.

Notes combined messaging and an application development environment, which set hearts a-fluttering in the early-to-mid 1990s. IBM laid out a then-record $3bn to acquire Lotus, which invented Notes, and drove the product to great prominence. IBM re-branded Notes’ back end as Domino and kept the Notes name for the client. But once Microsoft launched Outlook, bound it to Exchange and web-based development took off, both faded.
