+# Well Known Struct Tags
+## Background
+
+Go offers [struct tags](https://golang.org/ref/spec#Tag) which are discoverable via reflection. These enjoy a wide range of use in the standard library in the JSON/XML and other encoding packages. The community welcomed them and build ORMs, further encodings, flag parsers and much more around them.
+
+Since esp. while handling encodings and ORMs single sourcing data structures is beneficial for data structures.
+
+## Problem description
+Due to increased usage of Go and thus Go [struct tags](https://golang.org/ref/spec#Tag), clashes become inevitable.
+
+## Solution
+The list below is a best effort to document well known struct tags used by packages which available to the public.
+
+## Format of the list
+* Struct tag as extracted by calling https://godoc.org/reflect#StructTag.Get with this tag as the `key` argument.
+* Documentation link of this package using https://godoc.org
+
+### Example entry
+Tag | Documentation
+----|-----
+xml | https://godoc.org/encoding/xml
+
+### Change Management
+List entries can be added by anyone who creates a public package where a new tag is used.
+List entries can be removed when the links to the package documentation stops working or the author(s) of that package requests it.
