Depedencies

By collecting data on the projects within the WETO portfolio that use other tools within the portfolio, we can get a sense for the software projects that are at the “core” of the capabilities.

This network is divided into two types of connectivity:

1. Direct connections are software that are connected within the code, so they may communicate directly through API’s, share memory, and be distributed as a bundle.

2. Indirect connections are software that require the outputs of other tools in order to construct their inputs. These are connected through workflows rather than code.
