Steve/Christine,
The content could ask for LRS details and start sending statements. But, The very purpose of Tin Can is to track learning experiences. And to track learning experiences, the content would need to know who the learner is. It would be easiest for an LMS to provide that information. That is the reason most of these Tin Can packages work with an LMS. Now. you don't need a full blown LMS like Blackboard, you could use a simple plugin like GrassBlade xAPI Companion to Launch Captivate Tin Can content on WordPress.
Alternatively, you could use a single user information, (or may be a form?), to get the users info, and launch the Captivate content with using the TinCan's url format. Here is a guide for it: http://scorm.com/wp-content/assets/tincandocs/Incorporating-a-Tin-Can- LRS-into-an-LMS.pdf
If you do it yourself on a html page, these would be the steps:
1. Unzip the package.
2. Find the tincan.xml file.
3. Read it to know the launch file.
4. Build the url (Check the PDF above)
5. Launch the launch file in browser along with the URL string.
I hope that helped.
