geo cheatsheet
geo properties and how to use them.
Properties (Class Names)
- geo {1}
- latitude?
- longitude?
Key
Based on Perl's standard quantifiers:
| bold {1} | MUST be present exactly once |
| italic* | OPTIONAL, and MAY occur more than once |
| + | MUST be present, and MAY occur more than once |
| ? | OPTIONAL, but MUST NOT occur more than once |
| [square brackets] | list of common values |
| (parentheses) | data format |
| # | comment |
| ! | awaiting documentation |
Notes
- The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119.
- Coordinates MUST use the datum of WGS84.
- If latitude is present, so MUST be longitude, and vice versa.
- Coordinates MAY be combined a single <abbr> element; then the latitude and longitude MUST be separated by a semicolon in the title attribute and latitude MUST be first:
<abbr class="geo" title="37.386013;-122.082932">home</abbr>
- Best practice is that the same number of decimal places SHOULD be used in each value, with trailing zeroes if applicable.
- Some sources for latitude/ longitude coordinates
