Smile is a computer data interchange format based on JSON. It can also be considered a binary serialization of the generic JSON data model, which means tools that operate on JSON may be used with Smile as well, as long as a proper encoder/decoder exists for the tool. The name comes from the first 2 bytes of the 4 byte header, which consist of Smiley ":)" followed by a linefeed: a choice made to make it easier to recognize Smile-encoded data files using textual command-line tools.
Compared to JSON, Smile is both more compact and more efficient to process (both to read and write).[1] Part of this is due to more efficient binary encoding (similar to BSON, CBOR and UBJSON), but an additional feature is optional use of back references for property names and values. [2] Back referencing allows replacing of property names and/or short (64 bytes or less) String values with 1- or 2-byte reference ids.
Libraries known to support Smile include:

Run-length encoding (RLE) is a form of lossless data compression in which runs of data (consecutive occurrences of the same data value) are stored as a single occurrence of that data value and a count of its consecutive occurrences, rather than as the original run. For example, a sequence of "green green green green green" in an image built up from colored dots could be shortened to "green x 5". Run-length encoding is most efficient on data that contains many such runs, for example, simple graphic images such as icons, line drawings, games, and animations. For files that do not have many runs, encoding them with RLE could increase the file size. RLE may also refer to particular image formats that use the encoding. RLE is an early graphics file format supported by CompuServe for compressing black and white images, that was widely supplanted by their later Graphics Interchange Format (GIF). It is also the name of a little-used image format in Windows 3.x that is saved with the file extension rle, consisting of a run-length encoded bitmap; it was used as the format for the Windows 3.x startup screen.
JSON (JavaScript Object Notation, pronounced or ) is an open standard file format and data interchange format that uses human-readable text to store and transmit data objects consisting of name–value pairs and arrays (or other serializable values). It is a commonly used data format with diverse uses in electronic data interchange, including that of web applications with servers. JSON is a programming language-independent data format. It was derived from JavaScript, but many modern programming languages include code to generate and parse JSON-format data. JSON filenames use the extension .json. Douglas Crockford originally specified the JSON format in the early 2000s, and sent the first JSON message in April 2001 with Chip Morningstar.
BSON (; Binary JSON) is a computer data interchange format extending JSON. It is a binary form for representing simple or complex data structures including associative arrays (also known as name-value pairs), integer indexed arrays, and a suite of fundamental scalar types. BSON originated in 2009 at MongoDB. Several scalar data types are of specific interest to MongoDB and the format is used both as a data storage and network transfer format for the MongoDB database, but it can be used independently outside of MongoDB. Implementations are available in a variety of languages such as C, C++, C#, D, Delphi, Erlang, Go, Haskell, Java, JavaScript, Julia, Lua, OCaml, Perl, PHP, Python, Ruby, Rust, Scala, Smalltalk, and Swift.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
