'''Attribute-oriented programming''' ('''@OP''') is a technique for embedding metadata, namely [[attribute (computing)|attributes]], within program code.

== Attribute-oriented programming in various languages ==
=== Java ===
With the inclusion of [[Metadata Facility for Java]] (JSR-175)<ref>{{cite web | url=https://jcp.org/aboutJava/communityprocess/final/jsr175/index.html | title=The Java Community Process(SM) Program - communityprocess - final }}</ref> into the [[Java Platform, Standard Edition|J2SE]] 5.0 release it is possible to utilize attribute-oriented programming right out of the box.
[[XDoclet]] library makes it possible to use attribute-oriented programming approach in earlier versions of Java.

=== C# ===
The C# language has supported attributes from its very first release. These attributes was used to give run-time information and are not used by a preprocessor. Currently with source generators, you can use attributes to drive generation of additional code at compile-time.

=== UML ===
The [[Unified Modeling Language]] (UML) supports a kind of attribute called [[stereotype (UML)|stereotypes]].

=== Hack ===
The [[Hack (programming language)|Hack programming language]] supports attributes. Attributes can be attached to various program entities, and information about those attributes can be retrieved at run-time via reflection.
