Extracting data from Domino into PDF using XSLT and XSL:FO (Part 1)
Stephan H Wissel    

We all know "Notes doesn't print". Nevertheless the topic of document output and reports is not going away, even if I'd like to ban the reports. There are plenty of ready made tools, but today I'd like to start with home cooked reporting.
Why the effort? Using only tools that use open standards you gain more control over the whole process and you can use whatever deems fit. The downside: it is more things you need to know and might not be suitable for business users (but its great to torture interns). In the long run you have a portfolio of source transformations that you can combine potentially faster than any reporting tool. The general principle is "Extract Transform Render":
Extract Transform Render
  1. Extract:
    Whatever will pull out the XML for the second step will do the trick. For list type of rendering ?ReadViewEntries will do the trick or simple DXL exports. Quite often you might opt for some bespoke code to extract code with an eye of a fast and/or easy transformation phase. You also might consider to extract your data in conformance with an established international standard
  2. Transform:
    This step usually takes the XML from the extract phase and runs it through one or more XSLT transformations. XSLT is kind of IT Black Magic (other say it's just set theory) and can use quite some computing power. For high performance the pros use a dedicated applicance. Once you get the heck of XPath you can do some amazing reporting (e.g. "give me all sales guys where withing the last 5 sales of the 3 guys next to his ranking there was a carpenter")
  3. Render:
    Rendering is easy. The outcome of the transformation step will be XSL:FO which is a page description language. Use a free renderer or a commercial offering and a few lines of code. The output typically is a PDF file, but you can target graphic formats too.

Long Term Storage and Retention
Thu, Aug 14th 2014 6:14a   Stephan H Wissel
Not just since Einstein time is relative. For a human brain anything above 3 seconds is long term. In IT this is a little more complex. Once a work artefact is completed, it runs through a legal vetting and it either goes to medium or long term storage. I'll explain the difference in a second. This logical flow manifests itself in multiple ways in concrete implementations: Journaling (both eMail and databases), archival, backups, write-once copies. Quite often all artifacts go to medium term [read] Keywords: domino ibm notes application archive database email office wiki xml

Time stamped encrypted archives
Wed, Aug 13th 2014 9:12a   Stephan H Wissel
Developers use Version Control, business users Document management and consultants ZIP files. From time to time I feel the need to safeguard a snapshot in time outside the machine I'm working with. Since "storage out of my control" isn't trustworthy, I encrypt data. This is the script I use: #!/bin/bash ############################################################################ # Saves the given directory (%1) in an SSL encrypted zip file (%2) within # the personalFiles folder.

Designing a REST API for eMail
Sat, Aug 9th 2014 11:12a   Stephan H Wissel
Unencumbered by standards designed by committees I'm musing how a REST API would look like. A REST API consists of 3 parts: the URI (~ URL for browser access), the verb and the payload. Since I'm looking at browser only access, the structured data payload format clearly will be JSON with the prose payload delivered in MIME format. I will worry about calendar and social data later on. The verbs in REST are defined by the HTTP standard: , PUT, and DELETE. My base url would be http://localhost [read] Keywords: ibm email wiki

Running vert.x with the OpenNTF Domino API
Wed, Aug 6th 2014 1:11p   Stephan H Wissel
In the first part I got vert.x 3.0 running with my local Notes client. The mastered challenges there were 32 Bit Java for the Notes client and the usual adjustment for the path variables. The adoption of the OpenNTF Domino API required a few steps more: Set 2 evironment variables: DYLD_LIBRARY_PATH=/opt/ibm/notes LD_LIBRARY_PATH=/opt/ibm/notes Add the following parameter to your Java command line: -Dnotes.binary=/opt/ibm/notes -Duser.dir=/home/stw/lotus/notes/data -Djava.library.path=/opt/ib [read] Keywords: agent domino ibm lotus notes notes client applications eclipse java openntf

Workflow for beginners, Standards, Concepts and Confusion
Thu, Jul 24th 2014 10:12a   Stephan H Wissel
The nature of collaboration is the flow of information. So naturally I get asked about Workflows and its incarnation in IT systems a lot. Many of the question point to a fundamental confusion what Worflow is, and what it isn't. This entry will attempt to clarify concepts and terminology Wikipedia sums it up nicely: "A workflow consists of an orchestrated and repeatable pattern of business activity enabled by the systematic organization of resources into processes that transform materials, pro [read] Keywords: collaboration ibm applications email google openntf soa wiki

Adventures with vert.x, 64Bit and the IBM Notes client
Thu, Jul 17th 2014 8:12a   Stephan H Wissel
The rising star of web servers currently is node.js, not at least due to the cambrian explosion in available packages with a clever package management system and the fact that "Any application that can be written in JavaScript, will eventually be written in JavaScript" (according to Jeff Atwood). When talking to IBM Domino or IBM Connections node.js allows for very elegant solutions using the REST APIs. However when talking to a IBM Notes client, it can't do much since an external program ne [read] Keywords: connections domino ibm lotus notes notes client application development eclipse google java javascript oracle python wiki ubuntu

Cycle where?
Sun, Jul 13th 2014 1:12p   Stephan H Wissel
I like to cycle, I do that often and from time to time I have fun with traffic participants. One of the interesting challenges are multi-lane crossings (note to my overseas readers: Singapore follows the British system of driving on the left, so cyclists are supposed to cycle on the left edge of the road - which makes me edgy in some situations. So for right driving countries, just flip the pictures) where the outer lane allows more than one direction. Like these: Road rules do require the [read] Keywords: google wiki

From XML to JSON and back
Fri, Jul 11th 2014 8:12p   Stephan H Wissel
In the beginning there was csv and the world of application neutral (almost) human readable data formats was good. Then unrest grew and the demand for more structure and contextual information grew. This gave birth to SGML (1986), adopted only by a few initiated. Only more than a decade later (1998) SGML's offspring XML took centre stage. With broad support for schemas, transformation and tooling the de facto standard for application neutral (almost) human readable data formats was established [read] Keywords: application java javascript server wiki xml xslt

The folly of root cause analysis
Wed, Jul 9th 2014 6:12a   Stephan H Wissel
IT support's dealing with management is a funny business. Whenever something goes wrong, support teams engage in "defensive blaming" and the elusive quest for a root cause. I've seen this quest (and blaming god and country along the way if it doesn't appear) taking priority over problem resolution and prevention. The twisted thought is: "If I'm not sure about the (single) root cause, I can't neither fix nor prevent it from happening again". Why is that a folly? It paralyses: If a pe [read] Keywords: application database google wiki
