This EIP defines a resolver profile for ENS that permits the lookup of arbitrary key-value
text data. This allows ENS name holders to associate e-mail addresses, URLs and other
informational data with a ENS name.
## Motivation
There is often a desire for human-readable metadata to be associated with otherwise
machine-driven data; used for debugging, maintenance, reporting and general information.
In this EIP we define a simple resolver profile for ENS that permits ENS names to
associate arbitrary key-value text.
## Specification
### Resolver Profile
A new resolver interface is defined, consisting of the following method:
function text(bytes32 node, string key) constant returns (string text);
The interface ID of this interface is 0x59d1d43c.
The `text` data may be any arbitrary UTF-8 string. If the key is not present, the empty string
must be returned.
### Initial Recommended Keys
Keys must be made up of lowercase letters, numbers and the hyphen (-). Vendor specific
services must be prefixed with `vnd.`.
- **email** - an e-mail address
- **url** - a URL
- **avatar** - a URL to an image used as an avatar or logo
- **description** - A description of the name
- **notice** - A notice regarding this name;
- **keywords** - A list of comma-separated keywords, ordered by most significant first; clients that interpresent this field may choose a threshold beyond which to ignore
