Thank you Lisa. You are right in thinking that I need to make changes to the database only. Data would be exchanged in the XML standard for geographic information (OpenGIS GML). The data is geometric so clients would need 2-D line editing functionality in the browser, much like a mini CAD application. Both locking and access control are essential. At first glance it seemed that webDAV would help here because of the webDAV LOCK / UNLOCK HTTP extensions and access control protocols. I could create a mapping between the database objects and URLs easily enough at the server. But this imposes restrictions on client. Clients would need to know the object IDs before locking - it is has to be specified as part of the URL in the LOCK request. From the clients perspective a lock request would be "lock all objects in this area" with the area specified and the object IDS not. I guess I could get webDAV to work for my application but I'm beginning to see that it's not the most appropriate technology. Stuart
