 Use of the Data
 
-1) All data pertinent to a specific coordinate reference system must
-   be copied without modification and all related pages/records must
-   be included;
-
-2) All components of this data set pertinent to any given coordinate
-   reference system must be distributed together (complete
-   distribution of all components of the data set is preferred, but
-   the OGP recognises the need for a more limited distribution);
-
-3) The data may not be distributed for profit by any third party; and
-
-4) The original source [OGP] must be acknowledged.
-
 The user assumes the entire risk as to the accuracy and the use of
-this data.  The data may be copied and distributed subject to the
-following conditions:
+this data. The data may be used, copied and distributed subject to the
+following conditions

+1. INFORMATION PROVIDED IN THIS DOCUMENT IS PROVIDED "AS IS" WITHOUT
 WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING BUT NOT
 LIMITED TO THE IMPLIED WARRANTIES OF MERCHANTABILITY AND/OR FITNESS

-With regard to (3) above, the data may be included within proprietary
-applications distributed on a commercial basis when the commerciality
-is based on application functionality and not on a value ascribed to
-the freely-distributed EPSG dataset.
+2. The data may be included in any commercial package provided that
+any commerciality is based on value added by the provider and not on a
+value ascribed to the EPSG dataset which is made available at no
+charge. The ownership of the EPSG dataset [OGP] must be acknowledged.
+
+3. Subsets of information may be extracted from the dataset. Users are
+advised that coordinate reference system and coordinate transformation
+descriptions are incomplete unless all elements detailed as essential
+in OGP Surveying and Positioning Guidance Note 7-1 annex F are
+included.
+
+4. Essental elements should preferably be reproduced as described in
+the dataset. Modification of parameter values is permitted as
+described in the table below [*] to allow change to the content of the
+information provided that numeric equivalence is achieved. Numeric
+equivalence refers to the results of geodetic calculations in which
+the parameters are used, for example (i) conversion of ellipsoid
+defining parameters, or (ii) conversion of parameters between one and
+two standard parallel projection methods, or (iii) conversion of
+parameters between 7-parameter geocentric transformation methods.
+
+5.  No data that has been modified other than as permitted in these
+terms and conditions shall be described as or attributed to the EPSG
+dataset
