With the thread going round about the applicability of XML to this project I hate to inject more buzzworditis, but, here it is anyway -
ldap. I am working on building a web based MMI. The question is wether or not to incorporate a ldap server to store and control access to the
services and information that is available thru the HMI. The idea being that ldap is the standard for maintaining directory services for networked devices or entities and controllers and instrumentation are fast morphing into networked devices. An example of how this would possibly be used would be to have tags be an entry in the ldap
database, from there the ldap database would give access to any services available for that tag, i.e. , real time data, historical data, instrument database, parts information from warehouse, manuals from document management system, etc. Any new functionality would just have to be registered for that tag(s) to be made available to all. I am not up to speed on ldap and from initial perusal it seems to be fairly complex. So the question is, is it worthwhile to pursue or not.
