Some notes from work..

Some thoughts from the early planning at P...


Clarification on the component model

We need to define the components with all their properties, relations and functions. Perhaps some patterns from the JSF model can be used.

How is Content stored in the repository? Same way as in View? Should we seperate the Content-objects from Areas until they are published? This is related to workflow and document process routines, I guess. Note that it is important to maintain a modifiable workflow in the tools. Some smaller business will require a 1-step towards publishing an article, larger enterprises will need an x-step process involving collaboration from several stakeholders (author, publisher, editor).


Area is a meta-wrapper for content which describes how the Content will appear live (online).

Different sorts of Areas include Site, Page, Frame, Category, and so on. Literally all sorts of seperating folders that show up in the site map.

Traditionally, an object in a CMS (an article) is defined with meta-data which defines the graphical View of the object. This is per MVC, wrong! A news-article is usually put in a news-folder. This adds meta-data to the object, saying "This object is part of the News-category.". This wouldn't be a problem if it wasn't directly connected to the View of the site. If you're article is independant of View, then how come it is lying in the news-folder? What if you want to publish the same article in another folder? You could fix it by inserting a reference, but that would be a hack.

TODO: Clarify the point above :)

An Area contains other Areas and/or a reference to Content (a content object. We used to call these components, but still haven't figured out a better name for them).


A Content object is independant of the view and the Area(s) in which it resides.

Typical content objects: Article, Post, Comment, Webshop-item, Announcement

Attributes: Privilegie[], Action[], MetaTag[], language, Text[], WorkflowStatus, Dates

Operations: search, syndicate, modify, publish, crudImage, crudText, , move, reference

Template (is applied through a renderer on a Content object, resulting in a live object. The result will typically be an XML-snippet, like HTML or WML, or perhaps pure text):

Types: Article (title, subtitle, ingres, main, images), ArticlePreview (title, subtitle, ingres, thumbnail)

Images

Types: Thumbnail, NormalImage, ResizedImage, Logo

Attributter: title, MetaTag[]


Text

Types: title, subtitle, ingres, preview, mai, date

Attributes: Text (er meta-data i seg selv)

Operations: Rename, edit, internationalize


Requirements

These could resolve in a couple of user stories that will affect the component model. We don't need to model stories for obvious and primitive CRUD operations, but nifty stories that are required by the uses.

Elaborate the use of modules and how we will combine Actions and Components. How many of the data object should be predefined?

Typical CMS features

User/privilege/credentials/DRM/group and role-management

User interface - Usability

Authoring/editing - Core functiona

Integration of content - The jig-zaw

Meta-data - Adding value to information

Work process - Gate-setting

Templates - The dresses of a CMS

Version management - PĂ„literlighet

Globalization - Internationalization (i18n)

Rendering (page-generation) - Dynamics

Searching - Searchability/Findability

Personalization - Portals

Privileges - Access to the CMS

Syndication - Sharing content

Cross-media-publishing - Variation of access


Typical roles:

Author - composes articles, posts pictures

Manger - Check, confirm and submit new content

Adminstrator - Manage users, groups, user settings and order of authorization

Web-desinger - Design web layouts, pictures and styles

Sys-integrator - System components, object linkings

Open source CMS evaluations

I have now seen three more or less serious open source CMS reviews. First guy to hit the field was Matt Raible ( 1 2 3 4 ), ending up with Drupal , Joomla , Magnolia , OpenCms and MeshCMS being runner-ups. Then there is OpenAdvantage that tries out a handful ( Drupal , Exponent CMS , Lenya , Mambo , and Silva ), including Plone which they use for their own site (funny/annoying that the entire site has no RSS-feeds, nor is it possible to comment on the articles), following Matt's approach by exluding many CMS that seem not to fit the criteria. It is somewhat strange that OpenAdvantage cuts away Magnolia because it "Requires J2EE server; difficult to install and configure; more of a framework than CMS", and proceed to include Apache Lenya in the full evaluation. Magnolia does not require a J2EE server. It runs on Tomcat just like Lenya does (maybe it's an idea to bundle Magnolia with Jetty to make it seem more lightweight). I'm still sure that OpenAdvant

What I've Learned After a Month of Podcasting

So, it's been about a month since I launched   GitMinutes , and wow, it's been a fun ride. I have gotten a lot of feedback, and a lot more downloads/listeners than I had expected! Judging the numbers is hard, but a generous estimate is that somewhere around 2000-3000 have listened to the podcast, and about 500-1000 regularly download. Considering that only a percentage of my target audience actively listen to podcasts, these are some pretty good numbers. I've heard that 10% of the general population in the western world regularly listen to podcasts (probably a bit higher percentage among Git users), so I like to think I've reached a big chunk of the Git pros out there. GitMinutes has gathered 110 followers on Twitter, and 63, erm.. circlers on Google+, and it has received 117 +'es! And it's been flattr'ed twice :) Here are some of the things I learned during this last month: Conceptually.. Starting my own sandbox podcast for trying out everythin

Encrypting and Decrypting with Spring

I was recently working with protecting some sensitive data in a typical Java application with a database underneath. We convert the data on its way out of the application using Spring Security Crypto Utilities . It "was decided" that we'd be doing AES with a key-length of 256 , and this just happens to be the kind of encryption Spring crypto does out of the box. Sweet! The big aber is that whatever JRE is running the application has to be patched with Oracle's JCE  in order to do 256 bits. It's a fascinating story , the short version being that U.S. companies are restricted from exporting various encryption algorithms to certain countries, and some countries are restricted from importing them. Once I had patched my JRE with the JCE, I found it fascinating how straight forward it was to encrypt and decrypt using the Spring Encryptors. So just for fun at the weekend, I threw together a little desktop app that will encrypt and decrypt stuff for the given password

The academical approach

Oops, seems I to published this post prematurely by hitting some Blogger keyboard shortcut. I've been sitting for some minutes trying to figure out how to approach the JavaZone talk mentioned in my previous blog-post. Note that I have already submitted an abstract to the comittee, and that I won't publish the abstract here in the blog. Now of course the abstract is pretty detailed on what the talk is going to be about, but I've still got some elbow room on how to "implement" the talk. I will use this blog as a tool to get my aim right on how to present the talk, what examples to include, what the slides should look like, and how to make it most straightforward and understandable for the audience. Now in lack of having done any presentations at a larger conference before, I'm gonna dig into what I learned at the University, which wasn't very much, but they did teach me how to write a research paper, a skill which I will adapt into creating my talk: The one

Git Stash Blooper (Could not restore untracked files from stash)

The other day I accidentally did a git stash -a , which means it stashes *everything*, including ignored output files (target, build, classes, etc). Ooooops.. What I meant to do was git stash -u , meaning stash modifications plus untracked new files. Anyhows, I ended up with a big fat stash I couldn't get back out. Each time I tried, I got something like this: .../target/temp/dozer.jar already exists, no checkout .../target/temp/core.jar already exists, no checkout .../target/temp/joda-time.jar already exists, no checkout .../target/foo.war already exists, no checkout Could not restore untracked files from stash No matter how I tried checking out different revisions (like the one where I actually made the stash), or using --force, I got the same error. Now these were one of those "keep cool for a second, there's a git way to fix this"situation. I figured: A stash is basically a commit. If we look at my recent commits using   git log --graph --
