Upgrading your triple

stores
It is required that you As described in the Jena upgrade document, it is advisable to reload any SDB and TDB triple stores when upgrading to Jena 3 . Whilst there are command line utilities to do this provided as part of Jena, these have shortcomings with scalability. Plus, they are inconvenient to use as you need to know how to connect to your triple stores to use them. To make this process easier, the VIVO team has developed a couple of tools to handle this process.
Dumping the triple stores
using the procedure and tools described below.

VIVO/Vitro uses two triple stores – a configuration triple store typically stored using TDB in <home>/tdbModels, and a content triple store typically stored using SDB in MySQL. The procedures described below assume that you are running this standard configuration. If you are not, you will need a custom procedure for upgrading your triple stores. |
Export the triple stores

First you need to export First you need to dump your existing Jena 2 triple stores. To do so, shutdown Tomcat, and use the jena2tools utility provided with VIVO 1.10, specifying the export command.
...
On execution, the program will find your Vitro or VIVO configuration within the vivo/vitro home directory, and get the necessary information to connect to your configuration triple store (usually <home>/tdbModels), and your content triple store (usually in SDB). If your triple store(s) are not SDB or TDB backed, then it will simply skip them.
It will then extract the contents of the available triple stores, and dump them to <vivo home dir>/dumps in TriG format.

jena2tools will be present in <vivo home dir>/bin when you install the 1.10.0 alphabeta. Alternatively, it can be downloaded here GitHub.

On execution, the program will find your Vitro or VIVO configuration within the home directory, as well as the dumps that you have created with jena2tools. It will import them into SDB or TDB triple stores, based on the configuration of your Vitro / VIVO instance.
jena3tools will be present in <vivo home dir>/bin when you install the 1.10.0 alphabeta. Alternatively, it can be downloaded here GitHub.
