Chapter 27. Rewards and Reuse > Lending Support

Lending Support

It really is not all that hard to understand the score. Reuse on any substantial scale begins with reusable component libraries. There are really only two basic problems involved in such libraries: getting things into them and getting things out again! For programmers to reuse components from a library, there must first be components in the library. Where do these come from?

Various models have been proposed and tried. One is simply to accept free donations from anyone willing to have their code published in the library. Some organizations have had trouble getting donations until they either offered to pay for them or at least promised that authors would not be hounded for maintenance or modification. This approach, a sort of “used-book store” model, appears to be inexpensive, building a large library with little or no direct investment in component development. In theory, components are generated as a side effect of regular development projects.
