The bane of multistep node forms are validation errors. But Drupal 7 has a cure. Not nice but a cure.

Slap #access = FALSE on form elements you dont want to see in the current step and then set up the Next button with #limit_validation_errors set to the elements you are about to see. The Prev button should get an empty #limit_validation_errors. Should field validation errors bother you, you can nuke those in hook_field_attach_validate.

That’s my personal list of WordPress security tips, based on many helpful resources and my own experiences of getting hacked. These certainly don’t apply to everyone, more could be added, and your mileage may vary, but hopefully this will help others avoid some of the problems I encountered. Be sure to look at other people’s advice as well and watch out for any WordPress security news.

We are developing a tool called ROC (Rapid Ontology Construction) (see our paper@ASWC'08), which is a tool that allows domain experts to quickly build a basic vocabulary for their domain, re-using existing terminology whenever possible. How this works is that the ROC tool asks the domain expert for a set of keywords that are 'core' terms of the domain, and then queries remote sources for concepts matching those terms. These are then presented to the user, who can select terms from the list, find relations to other terms, and expand the set of terms and relations, iteratively. The resulting vocabulary (or 'proto-ontology', basically a SKOS-like thesaurus) can be used as is, or can be used as input for a knowledge engineer to base a more comprehensive domain ontology on.
