EMF Validation Builder is an Eclipse plugin that automates the validation process at the time of saving. This means that resource problem markers are up to date as soon as you save your model. A dependency table is maintained, which allows the validation process to be re-run when necessary. In particular, the tool can be directly used with ECore model files.
Inspired by dd5sum, ddsum includes the following features: support for md5, sha1, sha224, sha256, sha384 and sha512 (plus any additional digests provided by OpenSSL); the ability to read source data and write it out while computing a message digest; the ability to compute multiple message digests with one pass of the source data; and the ability to verify that a message digest matches the data you have.
