1. 4D Plug-in SDK is Now Open Source

To the delight of 4D plug-in developers in the audience and beyond,
Christophe Keromen announced during the Welcome keynote at 4D Summit
2009 the open source availability of 4D Plug-in SDK.

"Now, sources will be publicly hosted at http://sources.4d.com," said
Keromen. "All the documentation will be available there. And all of the
source code will be available through Subversion Client. You can use
free clients like Tortoise on Windows and svnX on Mac OS X."

The site provides a Wiki, submission guidelines, and access to the
source, at

Discussions take place on the existing 4D Plug-in Mailing List 4D
Plug-in Mailing List at

2. Tech Note Central

This week's topic: Using the Amazon Product Advertising API with 4D

http://kb.4d.com/search/assetid=75942

The purpose of this Technical Note is to illustrate how advanced Web
Services Client functionality can be implemented in 4D. Amazon’s Product
Advertising API is used as an example, as the service requires extra
coding in order to be called from 4D. More specifically, HMAC-SHA256
digest signatures, REST type web services, complex SOAP headers and
other topics related to web services are discussed in this document.

This is only a sample of the many valuable Tech Notes that are available
to 4D Partners in the 4D Knowledgebase. There are many more advantages
to becoming a 4D Partner. Visit 4D Partner Central for more information.
