 Open-core: The open-core commercialization model provides access to new features only to paying customers. Rather than essential functionality, this refers to optional features such as a nicer user interface or early access to new features. Some variants of this model use a time delay for new features, where paying users have access to new features sooner than those using the fully OSS version. Practically, the implementation of this strategy often involves the creation of a private, upstream fork of the OSS code repository. New features are then added to the private fork and synced to the OSS version at a later date. Such a strategy can also be used by academic labs looking to protect new features while preparing for publication and until a manuscript is accepted. Although we advocate for developing those features in the open, we recognize that there are instances where this is not practical. For example, when a junior researcher is publishing a novel algorithm, they may want to avoid the risk of having their work pre-empted by others. Similarly, collaborators may request that the software be kept private to prevent other researchers from using it and publishing their findings first. While we believe that these situations are rare in the proteomics community, they could lead to the original researchers losing recognition and credit for their work. The open-core model is quite common, and in proteomics, it is used for ScaffoldDIA from Proteome Software: the open-source core of ScaffoldDIA is EncyclopeDIA .
