geo cheatsheet
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
- If latitude is present, so MUST be longitude, and vice versa.
- If the secondary classes are omitted, the two values MUST be comma separated and latitude MUST be first:
<span class=geo">37.386013,-122.082932</span> - The same number of decimal places SHOULD be used in each value.
- Coordinates use the datum of WGS84.
