The contract books, kept in Batavia, contained copies of the various treaties and contracts the Dutch East India Company made with other parties in their area of operations. Each of those contracts is published in printed source publications. This collection of three datasets contains short descriptions of all the contracts, and an index on places and people mentioned or relevant.
For modern perspectives on these treaties, be sure to look at the Historical Treaties of Southeast Asia project.
CC BY-NC-SA and scientific datasets
CC BY-NC-SA requires attribution, restricts use to non-commercial purposes, and requires adaptations to be shared under the same licence. For scientific datasets, the NC (NonCommercial) clause can be problematic because it may prevent reuse by commercial researchers, industry, or organisations whose activities include commercial purposes. The SA (ShareAlike) clause can also complicate combining the dataset with other data or incorporating it into projects distributed under different licences. These restrictions may reduce interoperability, reproducibility, and broad scientific reuse. For datasets intended as open research infrastructure, more permissive licences such as CC BY or dedicated data licences may therefore be preferable.
