Just a note to say that even though the name "Sematic" is the same, this is not the same open source project as mine that I posted to Show HN about a week ago here: https://news.ycombinator.com/item?id=32364193.
Independently of the name collision, your Show HN looks good! and didn't get any attention. If you email me at hn@ycombinator.com, I'll send you a repost invite for it.
Your project is cool and has a cool name!
