An annotation is a note that is made while reading any form of text. This may be as simple as underlining or highlighting passages. Annotated bibliographies give people a source that is useful to an author in constructing a paper or argument. Creating these comments, usually a few sentences long, establishes a summary for and expresses the relevance of each source prior to writing. The term also has a special meaning in a number of other fields.

Not only code but text manipulated by a program can be annotated; e.g. A markup language (such as XML or HTML) is a modern system for annotating a text in a way that is syntactically distinguishable from that text.
A special case is the Java programming language, where annotations can be used as a special form of syntactic metadata in the source code.[1] Classes, methods, variables, parameters and packages may be annotated. The annotations can be embedded in class files generated by the compiler and may be retained by the Java virtual machine and thus influence the run-time behaviour of an application. It is possible to create meta-annotations out of the existing ones in Java, which makes this concept more sophisticated than in other languages like C#.[2]
Annotate aka Blame or Praise is a function used in source control systems such as Team Foundation Server and Subversion to determine who committed changes to the source code into the repository. A person, who is annotated, is blamed for committing changes to the source code into the repository which caused the program to fail or behave in an unintended fashion.
Since the 1980s, molecular biology and bioinformatics have created the need for DNA annotation. DNA annotation or genome annotation is the process of identifying the locations of genes and all of the coding regions in a genome and determining what those genes do. An annotation (irrespective of the context) is a note added by way of explanation or commentary. Once a genome is sequenced, it needs to be annotated to make sense of it.
For DNA annotation, a previously unknown sequence representation of genetic material is enriched with information relating genomic position to intron-exon boundaries, regulatory sequences, repeats, gene names and protein products. This annotation is stored in genomic databases as Mouse Genome Informatics, FlyBase, and WormBase. Educational materials on some aspects of biological annotation from this year's Gene Ontology annotation camp and similar events are available at the Gene Ontology website.[3]
The National Center for Biomedical Ontology (www.bioontology.org) develops tools for automated annotation[4] of database records based on the textual descriptions of those records.
As a general method, dcGO [5] has an automated procedure for statistically inferring associations between ontology terms and protein domains or combinations of domains from the existing gene/protein-level annotations.
In the digital imaging community the term annotation is commonly used for visible metadata superimposed on an image without changing the underlying master image, such as sticky notes, virtual laser pointers, circles, arrows, and black-outs (cf. redaction).
In the medical imaging community, an annotation is often referred to as a region of interest and is encoded in DICOM format.
In the United States, legal publishers such as Thomson West and Lexis Nexis publish annotated versions of statutes, providing information about court cases that have interpreted the statutes. Both the federal United States Code and state statutes are subject to interpretation by the courts, and the annotated statutes are valuable tools in legal research.
In linguistics, annotations include comments and metadata; these non-transcriptional annotations are also non-linguistic. A collection of texts with linguistic annotations is known as a corpus (plural corpora). The Linguistic Annotation Wiki[6] describes tools and formats for creating and managing linguistic annotations.
