| Value of the Code | Descriptive Term of the Code | Definition of the Code |
|---|---|---|
| Numeric | Numeric | Data consisting largely of values expressed as digits from 0 to 9 and, optionally, signs for negative values, decimal points, or letters only when intended to represent numbers (for example, A-F or a-f in hexadecimal). |
| Text | Text | Data consisting largely of text, including letters, numbers, and special characters or symbols used in writing for punctuation, abbreviation, etc. For example, interview transcriptions, narratives or essays written by study participants, newspaper articles, etc. |
| StillImage | Still image | Static images, such as graphs, drawings, photographs, diagnostic/medical images like X-rays, etc. |
| Geospatial | Geospatial | Geospatial data are any type of data with spatial coordinates that allow them to be mapped to the Earth's surface. They can represent physical objects, discrete areas or continuous surfaces. Discrete geospatial data are usually represented using vector data consisting of points, lines and polygons, while continuous geospatial data are usually represented by raster data, consisting of a grid of cells that each has its own value. Any number of applications in a wide range of areas produce geospatial data, such as GIS, Remote Sensing equipment, GPS units, archaeological total stations, manual mapping and computer-aided design (CAD), in a number of formats, including images, vector, text, and tabular data. Vector-based geospatial data include tables listing archaeological sites along with their coordinates, text-based files (e.g., XML) containing coordinates and topology for historic road networks, voting figures for political parties by administrative area. Raster-based geospatial data include satellite images, aerial photographs, scanned maps, and digital maps of elevations, vegetation, land-use, sea surface temperatures, air pollution, soil-types, etc. |
| Audio | Audio | Recorded sound, including voice, music, etc. |
| Video | Video | Moving images. May include films, animation, digital recordings, visual output from simulations, recorded television programs, etc. May be mute or may include synchronized sound. |
| Software | Software | Computer program(s) in source code (human-readable) or compiled form. |
| InteractiveResource | Interactive resource | A resource requiring interaction from the user to be understood, executed, or experienced. For example, training modules, query/response portals, files that require action from the user, etc. |
| ThreeD | 3D | Virtual three-dimensional representations of objects, architecture, places, etc. |
| Other | Other | Use when the kind of data format is known, but not found in the list. |
