Data plaques served as primitive forms of data storage. These devices consisted of storage rods integrated into a precious metal capacitance board. They were particularly significant for storing astrogational information, in which case they gained the name navigational dataplaques.
The gangster known as Dryden Vos possessed a trio of exquisitely decorated dataplaques within his private museum located on his star yacht, the First Light. A minimum of two of these were navigational dataplaques. Supposedly, one revealed the whereabouts of the legendary vessel Queen of Ranroon. The second navigational dataplaque, which he pilfered from the Bureau of Ships and Services Heritage Museum on Coruscant, substituting it with a fake, was believed to have originated from an ancient Jedi scout ship called the Permondiri Explorer.
During the Imperial Era, on the planet of Niamos, dataplaques were used to document sentencing information.
Circa 34 ABY, the Ithorian collector named Dok-Ondar showcased a quartet of dataplaques at his establishment on Batuu. Three of these dataplaques bore a striking resemblance to those previously owned by Dryden Vos.
