# 1. Introduction

### What is a BioProject?

**BioProject** is a central framework in K-BDS that connects and organizes diverse biological data generated from a single research initiative.\
It acts as a top-level container that provides an overview of the research, offering a single entry point to access related datasets across multiple K-BDS databases.

A BioProject can be established by a single research group or a consortium and serves as a reference unit that links all associated data — including sequencing, omics, chemical, imaging, and generalist data — under one research context.

### Why Register a BioProject?

Registering a BioProject ensures that various types of data produced from the same study are **contextually connected and traceable**.\
This linkage provides several important benefits:

* **Integrated data access:** Easily find and access all related datasets (e.g., genome, transcriptome, proteome) under one project.
* **Reproducibility and citation:** Provide a unified reference ID that can be cited in publications, enhancing reproducibility and scientific transparency.
* **Data interoperability:** Enable cross-database linking, improving the discoverability and reusability of your data.
* **Efficient project management:** Organize complex multi-omics and cross-disciplinary data under a single project framework.

### What Types of Data Can a BioProject Include?

A BioProject supports a wide range of biological and biomedical data generated from comprehensive research efforts, including:

* Genomics data (sequence read, functional genomics data, nucleotide and assembly, variation) 
* Proteomics data from mass spectrometry (MS)
* Metabolomics data from MS/NMR
* Chemical data (structure, assay, profiling) 
* Bio-imaging data (optical, EM, MR, CT, EPhys, etc.) 
* Pre-clinical data 
* Others (generalist)

### Relationship with Other Registration Units

In K-BDS, a BioProject serves as the **top-level registration unit** and connects to other components in the data submission ecosystem:

* **BioSample:** Provides detailed information about the biological source materials (e.g., organism, tissue, environment).
* **KRA (Korea Sequence Read Archive):** Stores raw sequencing data.
* **KNA (Korea Nucleotide Sequence Archive):** Stores assembled nucleotide sequences.
* **KEA (Korea Expression Archive):** Manages gene expression and functional genomics data.
* **KSO (Korea Spatial Omics):** Handles spatial transcriptomics and multi-omics spatial data.
* **Other databases:** Such as proteomics, metabolomics, chemical profiling, bio-imaging, and pre-clinical archives.

This hierarchical structure ensures that each dataset is properly linked back to the research context, making the BioProject the central node in the K-BDS data ecosystem.

> 💡 **Tip:** Think of a BioProject as the "home page" for your research. It tells the story of your study and organizes all associated data — no matter how diverse — into one accessible and citable reference point.
