+# PHP Simple Features SQL
+
+Build SFA-SQL (SQL/MM) expressions using SFA-CA syntax.
+
+
+
+## Terminology and standards
+
+- **SF** — [Simple Features](https://en.wikipedia.org/wiki/Simple_Features),
+the geometries and the interface to interact with them.
+- **SFA** — Simple Feature Access, same thing as Simple Features.
+- **WK** — "well known" formats like WKT, WEKT, WKB, EWKB.
+
+The main standards considered in this project ar the OpenGIS ones:
+
+- https://www.ogc.org/standards/sfa
+- https://www.ogc.org/standards/sfs
+
+Also see ISO 19125 (SFA) and ISO 19107 (spatial schema).
