The Semantic Web is coming to a TYPO3 installation near you. During the TYPO3 Transition Days 2011 in Berlin a couple of Developers—including me—discussed about how to implement some aspects of the Semantic Web Stack for TYPO3. One of the first outcome is the new Extension “semantic” providing a SPARQL Client.

Inspired by the SPARQL Query Result Parser written by Daniel Alexander Smith and published on the Enakting Blog, I just wrote an implementation in PHP. It utilizes the performant event based XML parser of PHP. In contrast to the original implementation written in Python, the current version below supports also the “datatype” and “xml:lang” attribute of literal types. read more »
Writing a book is a huge project. I never believed those people saying “Just double the time of your first estimate”. Now, after the book is finally available I would say they are wrong. You have to increase it threefold.
The book about Extbase and Fluid was written in close collaboration with Sebastian Kurfürst (core developer of Fluid) and Inken Kiupel (reader). We hope that it encourages the developers of TYPO3 extensions to get in touch with the fascinating concepts of FLOW3. And we hope that the book eases the migration to TYPO3 v5 (that’s what Extbase is all about).
We are aware of the fact that many of the English speaking TYPO3 developers are eagerly waiting for more Books about Extbase and Fluid published in English. Sebastian Kurfürst and I are currently investigating the best way to to get the book translated into English to be published on typo3.org.
If you have any questions regarding the book, or found some typos (at least 3), feel free to use the comments facility (if it is positive ;-) ) or write me an e-mail. I am really looking forward to hear from you.

Extbase supports very well the idea of Domain-Driven Design. It supplies a Repository class to comfortably fetch your objects from. Some handy methods are already implemented. read more »
Extbase is the new frame-work for TYPO3 extension developers introduced in TYPO3 v4.3. In this article I will give you a brief overview over the persistence layer of Extbase. It falls into different (sub)layers — each of the with different responsibilities. Let’s start our journey from the top level. read more »
The upcoming Version 5 of TYPO3 is rewritten from scratch. It is based on a new framework called FLOW3. With TYPO3 v5 the [API|Application Programming Interface] will change completely. There are also a couple of new programming paradigms and patterns. Personally, I am very enthusiastic about the “new way”.
The past couple of months I had numerous discussions about the new version and how to migrate from TYPO3 v4 to v5. And I had to realize that there are several reservations and concerns about all the new things to learn. All of them have to be taken into account to keep the community healthy.

Domain Driven Design is—by experience—a strong concept and a good foundation to build TYPO3 extensions upon.
Domain-driven design (DDD) is an approach to the design of software, based on the two premises that complex domain designs should be based on a model, and that, for most software projects, the primary focus should be on the domain and domain logic [...].
The domain represents structure, knowledge and data. A content management system (CMS) like TYPO3 has to handle the data of the domain with respect to the domain knowledge. It aggregates the data, and visualizes it as a content of an output format.
A question emerges: How should the data stored in a domain be mapped on the content of the output? read more »
Today’s development process of a TYPO3 extension comprises (usually) the following steps:
This ends up in an extension design which is hard to maintain – especially for larger projects. A more modern approach uses the Model View Controller Pattern. read more »
