| 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 has built ORMs, further encodings, flag parsers and much more around them since, especially for these tasks, single-sourcing is beneficial for data structures. |
| Due to increased usage of Go and thus Go [struct tags](https://golang.org/ref/spec#Tag), clashes become inevitable. |
| The list below is a best effort to document well-known struct tags used by packages which are available to the public. |
| * 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 |
| xml | https://godoc.org/encoding/xml |
| 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. |
