Some interesting info about this site

QCDB is a web-based generic database package designed especially to house quan- titative and structural information. It was motivated by the need for centralised access to such results for development of mathematical models, but its usefulness extends to the general research community of both modellers and experimentalists.

Unlike most existing databases, experimental and observational results curated in QCDB are supplemented by comments from the experts who contribute input to the database, giving their evaluations of experimental techniques, breadth of validity of results, experi- mental conditions, and the like, thus providing the visitor with a basis for gauging the quality (or appropriateness) of each item for his/her needs.

Curated data may be not only numerical values, but also qualitative results, images, or even animation files.
