Simple Data Format (SDF) is a platform-independent, precision-preserving binary data I/O format capable of handling large multi-dimensional arrays. It was written in 2007 by George H. Fisher, a researcher at the Space Sciences Laboratory at UC Berkeley, and released under the GNU General Public License.

RSS is a web feed that allows users and applications to access updates to websites in a standardized, computer-readable format. Subscribing to RSS feeds can allow a user to keep track of many different websites in a single news aggregator, which constantly monitor sites for new content, removing the need for the user to manually check them. News aggregators can be built into a browser, installed on a desktop computer, or installed on a mobile device.

The Super Dimension Fortress Macross: Flash Back 2012 is a 1987 collection of music videos from The Super Dimension Fortress Macross animated television series (1982–1983) and the Macross: Do You Remember Love? theatrical film remake (1984). Released to commemorate the fifth anniversary of the series, it also contains several minutes of new footage that depicted story-events that were initially planned, but not animated for the endings of the television series, and the film. Preliminary designs were created for these story events in the production of the earlier works, but Flash Back 2012 was the first time that these events were animated . The premise of the collection is a farewell concert by Lynn Minmay, who is leaving the Earth on its first long-distance colony vessel, Megaroad-01.
Standard Delay Format (SDF) is an IEEE standard for the representation and interpretation of timing data for use at any stage of an electronic design process. It finds wide applicability in design flows, and forms an efficient bridge between dynamic timing verification and static timing analysis.
Comma-separated values (CSV) is a text file format that uses commas to separate values. A CSV file stores tabular data in plain text, where each line of the file typically represents one data record. Each record consists of the same number of fields, and these are separated by commas in the CSV file. If the field delimiter itself may appear within a field, fields can be surrounded with quotation marks.
Hierarchical Data Format (HDF) is a set of file formats designed to store and organize large amounts of data. Originally developed at the U.S. National Center for Supercomputing Applications, it is supported by The HDF Group, a non-profit corporation whose mission is to ensure continued development of HDF5 technologies and the continued accessibility of data stored in HDF.
On the World Wide Web, a web feed is a data format used for providing users with frequently updated content. Content distributors syndicate a web feed, thereby allowing users to subscribe a channel to it by adding the feed resource address to a news aggregator client. Users typically subscribe to a feed by manually entering the URL of a feed or clicking a link in a web browser or by dragging the link from the web browser to the aggregator, thus "RSS and Atom files provide news updates from a website in a simple form for your computer."
A chemical file format is a type of data file which is used specifically for depicting molecular data. One of the most widely used is the chemical table file format, which is similar to Structure Data Format (SDF) files. They are text files that represent multiple chemical structure records and associated data fields. The XYZ file format is a simple format that usually gives the number of atoms in the first line, a comment on the second, followed by a number of lines with atomic symbols and cartesian coordinates. The Protein Data Bank Format is commonly used for proteins but is also used for other types of molecules. There are many other types which are detailed below. Various software systems are available to convert from one format to another.
Chemical table file is a family of text-based chemical file formats that describe molecules and chemical reactions. One format, for example, lists each atom in a molecule, the x-y-z coordinates of that atom, and the bonds among the atoms.
Stata is a general-purpose statistical software package developed by StataCorp for data manipulation, visualization, statistics, and automated reporting. It is used by researchers in many fields, including biomedicine, economics, epidemiology, and sociology.
Microsoft SQL Server Compact is a compact relational database produced by Microsoft for applications that run on mobile devices and desktops. Prior to the introduction of the desktop platform, it was known as SQL Server for Windows CE and SQL Server Mobile Edition.
The Spatial Data File (SDF) is a single-user geodatabase file format developed by Autodesk. The file format is the native spatial data storage format for Autodesk GIS programs MapGuide and AutoCAD Map 3D. As of 2014 SDF format version SDF3 uses a single file. Prior versions of the format required a spatial index file (SIF), with an optional key index file (KIF) to speed access to the file.
Ray marching is a class of rendering methods for 3D computer graphics where rays are traversed iteratively, effectively dividing each ray into smaller ray segments, sampling some function at each step. For example, in volume ray casting the function would access data points from a 3D scan. In Sphere tracing, the function estimates a distance to step next.
The Syrian Democratic Forces (SDF) is a coalition of ethnic militias and rebel groups which serve as the official armed force of the rebels and militants in Autonomous Administration of North and East Syria (AANES). A US formed and backed alliance of forces formed during the Syrian civil war composed primarily of Kurdish militias with some Arab, Assyrian/Syriac, Armenian, Turkmen and Chechen militias.
