xsd:hexBinary typed literals appear to be stored as actual strings

[ebremer]

xsd:hexBinary typed literals appear to be stored as an actual string rather than converted to binary. This seems to be an opportunity to get further compression.

Same seems to be true for xsd:base64Binary

Fair point! The gain would be minimal though, unless you have a bunch of those. Would you mind submitting a PR?

[ebremer]

I would have a quite a bunch. Does HDT's design allow for (if coded up) storage of the hexbins and base64's as actually binary data? If so, I would pursue it if it would be a welcome modification.

[mielvds]

It would! But it would also introduce a breaking change in the HDT files, meaning we'd have to move up a version and also reflect the changes in the C++ version. Not sure if that's worth it ATM without other improvements to release. That said, a branch is always welcome, ready to be included in a next release.
