In about a year, this post attracted 4 likes and no other responses. Does the lack of discussion mean the topic is unimportant to the larger community, or perhaps what I wrote is simply so far off target that people didn't see it as worthy of their time?
My hope, originally, had been that the metadata I suggest, and its associated recursive checking, can be incorporated into the SPM. Although I'd posted there, it was suggested creating this as a new topic. Perhaps there's a place for "SPM Evolution" discussion I've missed?
