Hello Martin,

It is really pleasing to hear such a commitment from some one deeply =
engaged in OGC. While I agree with you on the influence on a younger =
project and also the impact an open community process like Apache can =
have. I personally respect OGC as a governing organization and as a =
standards defining body. But we all could not deny the fact that =
community rallied behind OGC and produced some good software. I am =
curious to learn how will community respond to Apache SIS vs any =
software endorsed by OGC? Do you see SIS positioning itself as a =
reference implementation for the OGC standard?=20

Thanks,
Suresh
