What is a CMS?

A CMS is a Content Management System 鈥 a system to help you manage your content. While the individual words of a 鈥Content Management System鈥 are easily understood, when used together, as a term, they take on a specific meaning.听
If you have a collection it can sometimes be hard to find a particular item, so it can help to organize your collection using a system. You might sort your 鈥榗ontent鈥, say alphabetically or chronologically, to help you find things more easily and manage it more effectively.听
That is a 鈥榤anagement system鈥 for your 鈥榗ontent鈥 鈥 but it isn鈥檛 what we mean when we talk about a 鈥楥ontent Management System鈥 or 鈥楥MS鈥.听
Specifically a CMS is a software system or platform used by businesses to manage their digital content 鈥 be it web pages, documents, images or videos. Businesses may have hundreds if not thousands or even tens of thousands of pieces of digital content that they need to organize and access.听
By having this content in a system the business can manage it for its needs 鈥 for example to control who has access to what content, decide where the content will appear, see when it was last updated and so on.
What do you use a CMS for?听
There are three main ways that businesses use CMSs.听
- To create, edit, manage and deliver content to their digital channels such as websites and mobile apps, but also in-store displays or on-board flight entertainment systems to name but a few.
- To help staff work more effectively and share knowledge across teams, divisions, or indeed the entire organization, by being able to create, edit, collaborate and share content with one another through an intranet or knowledge hub.
- To work more efficiently with partners or other external stakeholders by making content easily accessible to all parties through an extranet or portal.听
Although largely unheralded, CMSs play a fundamental role in business today 鈥 neither the digital economy nor 鈥榃orking From Home鈥 would be able to function anywhere near as effectively without them. They help businesses to streamline and automate the processes involved in producing and distributing content 鈥 enabling staff to work far more efficiently and customers to enjoy better online experiences.
Different types of CMSs explained
The first CMS is widely acknowledged to be IBM鈥檚 FileNet system of the early 1990s, and since then many companies have developed CMSs for the market.听
Over the years, different types of CMSs have been developed. They vary in their particular purpose (use case), their architecture and licensing models.听
The key differences between them are laid out below.
Web Content Management (WCM)
versus
Component Content Management Systems (CCMS)听
- With a Web CMS you can create, edit and manage web pages. These started out as HTML pages, served up on external facing websites, but soon became popular to serve internal audiences too on intranets. These systems used to be 鈥榩age centric鈥, enabling you to edit a page as a whole. However, this model has severe limitations as it leads to copying/cloning content 鈥 for instance when a piece of information needs to be displayed in two areas of the website. Better Web CMSs now allow you to work with content as reusable items 鈥 the same content can be displayed in various places without having to copy it over each and every time.

- A Component Content Management Systems (CCMS)听is used to manage highly componentized content such as technical product information (user manuals for example) that have traditionally been published in print or as PDFs. Content reuse is the big driver behind using content 鈥榗omponents鈥. When Model B of a piece of equipment supersedes Model A, and only a few small content changes are needed, the majority of content can be reused without having to duplicate it. If for example the manual for Model A has 2,000 paragraphs of information, but you only need to edit 10 paragraphs to republish this as a new manual for Model B, you can quickly and easily reuse the other 1,990 paragraphs.
Nowadays the use case for CCMSs goes beyond print and PDF, since companies often want to publish this information online too as individual web pages or as snippets rather than as a chunky PDF. CCMSs are also increasingly being used for content broader than just technical documentation, such as the management of policies, procedures, guidelines etc. in non-technical industries.
Commercial versus Open Source CMSs听
- Commercial CMSs are the ones you buy from a vendor. They offer you either a license that you buy (perpetual or term license) or a subscription model. Because they build and maintain the software for you, you can contact their support desk in case of any problems, and depending on priority, they will fix it for you within an agreed timeframe.

- An Open Source CMS is a 鈥榝ree鈥 CMS product. You can download the software and use it without having to pay a license fee. There is a community of developers that builds and maintains it. Obviously it being free is great, but be aware that it does require technical skills to deploy and maintain it (you鈥檒l need IT professionals), and there is no guarantee that it will work for your unique circumstances. If it breaks, you鈥檙e depending on the community or your own IT staff to fix issues.
This model has evolved so there are now some open source products that can be used through a service provider, who can offer you a managed version of such a CMS, and provide you with a Service Level Agreement.

Headless versus head-on CMSs听
You often hear the term 鈥榟eadless CMS鈥 being used. The idea isn鈥檛 new. In fact a number CMSs from the early 2000s were already 鈥榟eadless鈥.听
So what is a 鈥榟eadless鈥 CMS?听
The 鈥榟ead鈥 is the website (or 鈥榳eb application鈥) that runs on top of the CMS. So a 鈥榟eadless鈥 CMS does not have a website as a presentation layer, whereas a 鈥榟ead-on鈥 CMS does. A 鈥榟eadless鈥 system exposes content via APIs (often in JSON format) as its main way of delivering content, whereas 鈥榟ead-on鈥 CMSs deliver their content through HTML pages, direct to a website.
There are pros and cons to both approaches 鈥 like the ability to do in-context editing of a web page with a head-on CMS and the ability to deliver content in multiple formats to multiple devices with a headless CMS 鈥 so these days you鈥檒l see hybrid CMSs being promoted, which combine the best of both worlds.
AI in content management
There are three key areas where Artificial Intelligence (AI) is being used in content management.
- AI for personalization. This is a key area where Web CMS technology starts to use AI to tailor content to the recipient much better. Based on browsing behavior and past interactions and preferences, the system tries to serve up content that is relevant to the visitor in that moment. In order to do so, a page-based CMS is simply not up to the job. The system needs to be capable of managing the content as individual items that can be dynamically assembled and reassembled into engaging, personalized digital experiences.

- Semantic AI.听This is a way to make content more 鈥榠ntelligent鈥 and make it easier to discover and search for. On one hand semantic AI helps content authors with automated tagging of content 鈥 typically according to a taxonomy, so that the content is consistently classified across the system. On the other hand it massively improves search results. It opens up the ability to find related content, based on what the user鈥檚 search intent is, rather than going by the exact words they are using to search with.
Semantic AI can be used in both Web CMSs and CCMSs.

- Generative AI. Since the introduction of ChatGPT, Generative AI - aka Gen AI 鈥 has seen a huge level of initial hype, and shortly after an accelerated adoption in a wide range of technologies, including content management systems. At this stage it definitely won鈥檛 replace content authors. Instead, it鈥檚 a tool used by them to speed up and automate certain tasks such as summarizing content, checking style and readability levels, and rephrasing content as needed. It typically acts as a 鈥榗o-pilot鈥 helping the author be more productive and create higher quality output. 听.
