If you look up the word "HEMiDEMi" in a dictionary, you probably won't find it. HEMiDEMi comes from the musical term "Hemi-demi-semi-quaver," which refers to a sixty-fourth note.
Hemi, Demi, and Semi all mean "half." Quaver means one-eighth. When multiplied together, they equal one-sixty-fourth.
So why name it HEMiDEMi?
You can break down HEMiDEMi into HEMi - DEMi. Since both HEMi and DEMi mean "half," we hope to harness the power of the internet to connect the two halves at either end of the web—those who didn't previously know each other but still need one another—through HEMiDEMi.
And this "half" could be information, people, objects, etc.
