ATOM Publishing Protocol (AtomPub): XML based format for reading and writing information with structured meta data. Properly implemented is makes heavy use of Dublin Core meta data descriptions. ATOM is behind a lot of data exchange and API including OData (the format Microsoft and SAP have committed to). There is Apache Abdera for Java, support for Atom in Dojo and even jQuery
OpenSocial: Framework to build applications for integrated experiences. The title might be a bit misleading, since it is much more than "add a share this" button to your page. It is a complete widget definition and interaction standard. Extends iWidgets. Both IBM Portal as well as the IBM XPages server will be both OpenSocial containers and widget contributors. Already today a Domino server cann serve a component in RCP Widget and iWidget format, so we can expect that the component model will support OpenSocial too
ActivityStreams: While OpenSocial defines interaction up to the UI level, ActivityStreams are the pipes feeding new information into your experience. The ver brief definition: ActivityStreams are ATOM data feeds that have at minimum the agreed set of attributes ad defined by the ActivityStreams working group. I expect ready ActivityStreams controls to first appear in the XPages Extension Library before they move to the product core control set
Last not least the IBM Social Business Toolkit: It brings all the above components together. The real remarkable aspect: As of today there is no shipping IBM product supporting the full API, nevertheless IBM provides a working test environment, so you can test and be prepared
From my training experience I can tell: If you grew up with web standards, developing on the XPages platform is fast and fun.
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
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:

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
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
Warriors of Light
Sun, Jul 20th 2014 11:15a Stephan H Wissel Inspired by Paulo Coelho's manual for the Warrior of the Light:
Warriors of Light
We were born from the stars
Descended from the heavens
Armed with compassion
Determined to end the suffering
Subjected to the human condition
Battling ignorance with wisdom
Laying our lives for the liberation from illusion
When you look in the mirror - remember!
You are one of us. [read] Keywords:
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:

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
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
