Scripts, textures, and models are some examples of source data files.

Source data are the raw assets which have not yet been converted into tags useable by the engine. They live under the data directory of your mod tools and include uncompressed textures, models and animations you have exported from your 3D software, and level scripts. In most cases, assets within data will have a corresponding tag under the same folder layout in tags.

The processes for importing these assets into tags, and the types of source data formats used, depends on the game. Some formats are common but others are generational. H1-H3/ODST differ between each other, but differ even more compared to later games like Reach, H2A, and H4.
