Digging deeper into CMS requirements (#1: Technical Requirements)

I recently posted about the fabled CMS requirements, providing my own categorization without any further elaboration on what the different req's imply.

Today I'm gonna fill in the holes on the first category, Technical Requirements:

Technical requirements are the obligatory basic needs of the environment, hardware and software hosting and maintaining the WCMS.

The successful deployment of a WCMS depends on many information infrastructural circumstances and politics like management priority, user acceptance and technical feasibility. As will be declared in a later post, the main requirement of a WCMS is extensibility, and the one who has to make use of this requirement is indeed the developer responsible for deploying and running the WCMS in-house of the intended organization or corporation.

The hardware requirements and costs have not been a main issue in my experiences with maintaining CMS. I therefore disregarded the still very crucial requirements of scalability, availability and security. When professionally auditing WCMS solutions these requirements must be considered.

The WCMS may rise or fall by the outcome of these developer tasks.

Deployment

Developers are responsible for installing the WCMS, not only the first time, but they are also the ones performing redeployment when upgrades are necessary or patches are released from the vendor. If the process is cumbersome, this will happen with a low frequency and lead to a compromised and outdated WCMS. If it is not easy to migrate old content from the old installation to a newer one, the developer will quickly tire of the process and opt to management for choice of a different WCMS,

Integration

Infrastructural services such as e-mail, user directories and existing services should often be interconnected into the WCMS, and this will perhaps be the largest task the WCMS developer is responsible for, depending on requirements and existing information systems within the organization. Larger ECM solutions often benefit from utilizing strategies of service-oriented architecture (SOA), making it easier to integrate new functionality as web-services into the system.

Templates

Default templates and skins are bound for change after acquiring the system. Company logo and themes must be applied, and the CSS-styles applied by the WCMS may not be of the same patterns as the company's graphical profile.

This is not as much a feature as it is a necessity. A company is often judged by the outlook and consistency of its web-site. While the web designers no longer need to author the content of web-sites, they still need full control of the design. Templates allow designing once, and then applying the same design to whole parts of the site in one action.

Older web design tools have created an inclination towards not using mesh templates, where the template is separated into header, footer, left panel, main column, right column, and so on. More modern web design tools have support for working on such composite page design.

Backup

A WCMS is a complex system, and since this type of software is a fairly modern family of information systems, it is prone to experience bugs and crashes where data loss is a risk. Many technicians would argue that the responsibility of making information backup lies outside the WCMS, but there is still a requirement for the content repository to be backup-able in an automated fashion. A home grown file system or smaller database repository may lack support for such tasks.

Monitoring

Monitoring consists of automatically computing statistics and numbers on server usage and display them to the developer in a readable format. For a web-site this includes keeping track of incoming requests from visitors. If site traffic is not monitored it becomes harder to evaluate the returns of the WCMS, and it will quickly loose its favor from the management which weighs the cost of sustaining against these returns.

Logging

Logs are the server's output on relevant activities and processes. If logging is not done properly, it becomes hard to trace the source of errors and crashes.

Most web-servers have tools for monitoring the number of visitors. Traffic can be measured in number of “visits” or “hits”, although number of hits can give a very misleading understanding of how much traffic the web-site is experiencing. Number of visits and average visit length is the correct way to report traffic.



So there you have'em. My next post under this tag will explain the next category: The functionality that provides the management parts of the system, like content creation, publishing, workflow and administration. Stay tuned!

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

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

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

Git tools for keeping patches on top of moving upstreams

At work, we maintain patches for some pretty large open source repositories that regularly release new versions, forcing us to update our patches to match. So far, we've been using basic Git operations to transplant our modifications from one major version of the upstream to the next. Every time we make such a transplant, we simply squash together the modifications we made in the previous version, and land it as one big commit into the next version. Those who are used to very stringent keeping of Git history may wrinkle their nose at this, but it is a pragmatic choice. Maintaining modifications on top of the rapidly changing upstream is a lot of work, and so far we haven't had the opportunity to figure out a more clever way to do it. Nor have we really suffered any consequences of not having an easy to read history of our modifications - it's a relatively small amount of patches, after all. With a recent boost in team size, we may have that opportunity. Also the need for be

Managing dot-files with vcsh and myrepos

Say I want to get my dot-files out on a new computer. Here's what I do: # install vcsh & myrepos via apt/brew/etc vcsh clone https://github.com/tfnico/config-mr.git mr mr update Done! All dot-files are ready to use and in place. No deploy command, no linking up symlinks to the files . No checking/out in my entire home directory as a Git repository. Yet, all my dot-files are neatly kept in fine-grained repositories, and any changes I make are immediately ready to be committed: config-atom.git     -> ~/.atom/* config-mr.git     -> ~/.mrconfig     -> ~/.config/mr/* config-tmuxinator.git       -> ~/.tmuxinator/* config-vim.git     -> ~/.vimrc     -> ~/.vim/* config-bin.git        -> ~/bin/* config-git.git               -> ~/.gitconfig config-tmux.git       -> ~/.tmux.conf     config-zsh.git     -> ~/.zshrc How can this be? The key here is to use vcsh to keep track of your dot-files, and its partner myrepos/mr for o
