Unfortunately the link is broken (404). I wasn't able to find Feikes Articles in any other location. The best alternative content/introduction on OSGI R7 annotations I could find is this one:

Hi all!

Unfortunately, the original article from Feike is no longer available on the Adobe blog.

Also the alternative document from helpx that I provided some time ago seems to be gone from it's original location.

If you are looking for resources on OSGI annotations, please check the following links:

• Feikes Article on the Internet Archive:
  https://web.archive.org/web/20200813034945/https://blogs.adobe.com/experiencedelivers/experience-man...
• The article from helpx has since been moved to this location:
  https://experienceleague.adobe.com/docs/events/experience-manager-gems-recordings/gems2018/using-osg...

Please note that both articles are from 2018. While the overall concept of OSGI annotations still holds true, not every detail will still be up-to-date and valid.

You might also want to look at these more recent blogs from 2021:

• https://kiransg.com/2021/11/07/aem-osgi-services-best-practices/
• https://redquark.org/aem/day-08-osgi-components-services/

And as for almost every important topic, there's also a blog post from @joerghoh on OSGI annotations (from 2019): https://cqdump.joerghoh.de/2019/01/03/from-scr-annotations-to-osgi-annotations/

Adobe's official documentation has a high-level introduction to OSGI that might also be a good starting point:

• https://experienceleague.adobe.com/docs/experience-manager-learn/cloud-service/underlying-technology...

If you are looking for information on how to use OSGI configurations, please refer to the following links:

• https://experienceleague.adobe.com/docs/experience-manager-65/deploying/configuring/configuring-osgi...
• https://experienceleague.adobe.com/docs/experience-manager-65/deploying/configuring/osgi-configurati...
• https://blog.osoco.de/2020/07/guide-on-using-osgi-configurations/

Hope that helps!
