Marshalling (also known as serialization) is the process of transforming the memory representation of an object to a data format suitable for storage or transmission. It is typically used when data must be moved between different parts of a computer program or from one program to another.

The opposite, or reverse, of Marshalling is called Unmarshalling (also known as deserialization).
- Marshalling is heavily used within Microsoft's Component Object Model (COM), where it is necessary for transporting data between processes and between apartments. The conversion between an unmanaged type and a CLR type, as in the P/Invoke process used in the .NET Framework, is also an example of an action that requires marshalling to take place.
- Additionally, Marshalling is used extensively within scripts and applications that utilize the XPCOM technologies provided within the Mozilla Application Framework. The Mozilla Firefox Browser is a popular application built with this framework, that additionally allows scripting languages to utilize XPCOM through Cross-Platform Connect (XPConnect).

The terms "marshalling" and "serialization" are not synonymous.
- To "marshal" an object means to record its state and codebase(s) in such a way that when the marshalled object is "unmarshalled," a copy of the original object is obtained, possibly by automatically loading the class definitions of the object. You can marshal any object that is serializable or remote. Marshalling is like serialization, except marshalling also records codebases. Marshalling is different from serialization in that marshalling treats remote objects specially.
- To "serialize" an object means to convert its state into a byte stream in such a way that the byte stream can be converted back into a copy of the object.

Maven is a software project management and comprehension tool. Based on the concept of a project object model (POM), Maven can manage a project's build, reporting and documentation from a central piece of information.

In computing, a regular expression is a string that is used to describe or match a set of strings, according to certain syntax rules.

Regular expressions are used by many text editors, utilities, and programming languages to search and manipulate text based on patterns. For example, Perl and Tcl have a powerful regular expression engine built directly into their syntax. Several utilities provided by Unix distributions—including the editor ed and the filter grep—were the first to popularize the concept of regular expressions. "Regular expression" is often shortened to regex or regexp (singular), or regexes, regexps, or regexen (plural). Some authors distinguish between regular expression and abbreviated forms such as regex, restricting the former to true regular expressions, which describe regular languages, while using the latter for any regular expression-like pattern, including those that describe languages that are not regular. As only some authors observe this distinction, it is not safe to rely upon it.

As an example of the syntax, the regular expression \bex can be used to search for all instances of the string "ex" that occur at word boundaries (signified by the \b). Thus in the string, "Texts for experts," \bex matches the "ex" in "experts," but not in "Texts" (because the "ex" occurs inside the word there and not immediately after a word boundary).

Many modern computing systems provide wildcard characters in matching filenames from a file system. This is a core capability of many command-line shells and is also known as globbing. Wildcards differ from regular expressions in that they generally only express very restrictive forms of alternation.
