One of the most interesting aspects of xAPI is the ability to model time.

There are many xAPI implementations that have been invested in over the last few years that for one reason or another are now in need of an update and you find that you need to move from one vendor’s LRS to another. But what do you do about all of that data that you’ve collected?

Yet Analytics has released two new open source libraries for xAPI Profile validation. The first is called Pan and is used to validate xAPI Profiles. The second is called Persephone and is used to validate xAPI statements against xAPI Profiles. Both libraries are distributed under the Apache 2.0 license.
