• LaSuli is the "client" which will enhance your web browser so that you can annotate web pages with categories,
• Argos is the "server" in which you will store your annotations to retrieve them later from other computers or to share them with colleagues.

• When you will get more and more documents, you will soon need a synthetic view of your annotations. This client, acting as your portfolio, is Porphyry.
• With a growing expertise in qualitative analysis and in your corpus, you will notice in the texts "markers" of a category. For example, in French, soi-disant, censé, aurait, pseudo could be defined as markers for the criticism category. Cassandre will allow you to define such "notional families" (cf. Luhn). For performance reasons, Cassandre requires that you store your texts in it, therefore it will be used also as your texts archive server.

Not for now, but we work very hard on this feature. The new protocol which will allow this is already in place for the communication between LaSuli/Porphyry and Argos.

Meanwhile, you can still use notional families with the previous versions of Porphyry and Cassandre.

"Analysis frameworks" are Hypertopic "viewpoints", and "categories" are Hypertopic "topics".

Hypertopic (and the former Porphyry model) was designed long before we thought of using it for sociology and qualitative analysis. Moreover, it is usable in very diverse domains where "viewpoint" and "topic" are relatively easy to understand.

In LaSuli, which is more specific to qualitative analysis, we had to change the terms "viewpoint" and "topic" because they were misleading (especially in sociology).
