New Feature: PDF Scrubbrush

While PDF is intended to provide an entirely portable mechanism for exchange of non-trvial documents. However, in practice documents created by the real-world variety of clients almost inevitably contain deviations from the PDF standard which create issues when the document is processed by other applications and platforms. To ensure maximum compatibility the scrub brush feature re-compiles documents on the server using the using the Poppler libraries.

Using AttachFS To Test XSLT Transforms

We have previously demonstrated testing format descriptions using AttachFS. Now with OpenGroupware Coils 0.1.49rc91 you can also list, retrieve, and test XSLT templates stored in the workflow engine [OIE]. XLST transforms are accessible via AttachFS requests at the URL /attachfs/workflow/xslt.

Getting A Route's Markup Via AttachFS

AttachFS provides a simple method to retrieve the representation or contents of an entity via a GET request for the object's identifier [even improper entities such as messages and attachments can be retrieved this way]. For simple clients this is often a more straight forward approach than WebDAV.

As of 0.1.49rc70 you can now retrieve the BPML markup of an OIE workflow by requesting the route's object id from AttachFS.

Easy StandardXML To JSON

Recemt commits to OpenGroupware Coils add a new jsonWriteAction action for OIE workflows. OIE has long had readJSON for serializing arbitrary JSON documents into XML. jsonWriteAction adds the ability to serialize StandardXML data into JSON documents [provided all the data-types represented in the StandardXML document can be persisted in JSON]. Date and date time values will be serialized as strings in the YYYY-MM-DDTHH:MM:SS format; date values will have a time value of "00:00:00'".

XPath Expression As Action Parameters

A new feature in the latest edition of OpenGroupware Coils [0.1.49rc67] is support for using XPath expressions as parameters for work-flow actions. When a work-flow action parameter begins with $XPath: the input message (which must be XML) is interrogated for the corresponding value prior to the action being performed. Evaluation of the XPath is performed after label substution allowing wild cards to be used to construct the query expression.

One use-case where this is frequently useful is when processing the "current" message within a foreach construct.

Using SSH/SCP From OIE

The OpenGroupware Integration Engine supplies three actions for utilizing the SSH protocol:
