A collaborative submission model for building high-quality data resources at scale through partnership
This paper presents a collaborative submission model, exemplified by CZ CELLxGENE Discover, which successfully scales the creation of high-quality biomedical data resources by partnering data contributors with dedicated curators to balance corpus size with metadata richness and quality.

Imagine you are trying to build the world's largest and most useful library of biological information to help scientists train smart computer programs (AI) and solve big medical mysteries.
The paper describes a major problem: You want a library with millions of books (a huge amount of data), but you also need every single book to be perfectly written, well-organized, and easy to understand (high quality and rich details). Usually, these two goals fight each other. If you just ask people to drop off their books, you get a massive pile, but it's a mess of torn pages and missing titles. If you try to organize everything yourself, you can only handle a few books at a time.
The Solution: The "Collaborative Submission" Model
The authors explain how they solved this by creating a team-up between two groups:
- The Researchers (The Contributors): These are the scientists who actually did the experiments. They know the "secret stories" behind their data but are too busy to spend hours formatting it for a public library.
- The Curators (The Partners): These are the library experts who know exactly how to organize, label, and standardize data so computers and other scientists can use it easily.
How It Works (The Analogy)
Think of it like a professional moving company helping someone move house.
- The Old Way (Contributor-driven): You ask the homeowner to pack every box, label every item, and drive the truck. They do it, but they might forget to label the "Fragile" boxes, or they might pack the kitchenware with the books, making it hard to find anything later.
- The Other Old Way (Resource-driven): The moving company tries to pack the house for you without asking the homeowner anything. They pack everything neatly, but they don't know which box contains the family heirloom or which book is a rare first edition. They might throw something important away or mislabel it.
- The New Way (Collaborative): The homeowner (Researcher) says, "Here is the heirloom, and here is the book I want to keep." The moving company (Curator) says, "Great, I'll pack that carefully, label it perfectly, and put it in the right truck."
Why It Works
- Best of Both Worlds: The researchers provide the "intimate knowledge" (the context), and the curators provide the "standardization" (the organization).
- Less Burden: The researchers don't have to do all the heavy lifting of formatting; they just share their knowledge.
- Better Quality: Because the curators are experts in making data reusable, the final result is a high-quality resource that is ready for AI training and complex analysis.
The Result
Using this partnership model, the CZ CELLxGENE Discover project has become a rapidly growing, high-quality "library" that scientists use to test new ideas, validate their findings, and build AI models. The paper argues that this specific way of working together is the key to building massive, reliable data resources that can last and grow over time, without sacrificing quality for quantity.
