Hi all.
I wanted to inform the tasks I worked on this week: Jan 17 - Jan 29 .
* Add suggested javadocs.
* Add suggested constants.
* Make EXIST constraints optional.
* Activate tests:
testNewInstance
testAutoCreateSchema
testPut
testBenchmarkExists
testGetNonExisting
testObjectFieldValue
* Write a blog (Career opportunities)
My code is here: https://github.com/mgov88/gora/tree/GORA-663
Regards,
Gaby
