I just added a new book to our compendium of documentation - IO Reference. http://tinkerpop.apache.org/docs/3.2.3-SNAPSHOT/dev/io/#_io_reference
It provides lots of samples (especially around GraphSON which will be helpful to GLVs i think) and some additional details that aren't in our standard reference documentation, which is a bit more user facing whereas this IO Reference is more for developers.I purposely didn't want to add this content to our Reference Docs as it would just blow out the length of it in a pretty big way. I probably need to polish up the Reference Docs now a bit more in the context of this, but that can happen on the way through code freeze. I think there's more details I could add, but this is a good stopping point for purposes of general review.
