How to build an App on SAFE Network?

API: an App can register a session with the network and retrieve a list of directories it has access to.
is this wrapping MaidSafe-Drive or MaidSafe-Network-Filesystem or something else?

The RegisterAppSession function isn’t a wrapper to anything. It merely helps someone connect to the launcher app to authenticate the current app and retrieve it’s DirectoryInfo objects which it can then use to store/retrieve data to those folders in the network via the NFS API.

I assume that once you have this you can use boost file system library to access these directories, is that correct?
if so, will the move to Rust change this interface or will it still be boost based?

boost-filesystem is just a C++ helper lib(obv a very useful helper lib but in essence just a helper lib) to access the filesystem in a machine. It doesn’t have anything specific to the network. Actually even in C++ you’ll only be using boost-filesystem if you wanted to access the VFS/Native drive from a C++ app. Now there are other filesystem helper libs in C++ too, so this is just one example. If we take a different language via the port’s, they would use their own helper libs to access the system’s filesystem.

Ports: contains support for several languages, with API wrappers for a NoSQL style API with PUT / GET (key-value) support, but nothing higher level, whereas I’m expecting it to have a bunch of higher level operations such as described in the Redis tutorial.
Can we expect something like Redis? Or is Ports a wrapper for the Maidsafe-Network-Filesystem RESTful API?
If Ports is to provide NoSQL, how close to Redis, and what kind of differences can App devs expect?

It’s easier to think of Ports as the equivalent to the current C++/RUST API’s for non C++/RUST App devs. So in essence the Ports project doesnt by itself set an objective to make stuff “easier”. We can have a completely detached project have it as it’s objective but Ports project merely opens the door to app devs coming from different languages to the network.

Maidsafe-Network-Filesystem: documents a RESTful API (put, get, delete and post). Is this what “Ports” is wrapping?

I think this might now be clearer after the previous answer as to the objective of the Ports project. So exposing the NFS API which was in C++ was indeed one of the things the Ports project dealt with for non C++ languages.

SAFE App Examples: there is no sample code at present, but some helpful information.

Sample code/examples will now almost get integrated as part of the individual projects themselves with rust which has a dedicated examples section for each module and in-line documentation examples. We should also see detached Examples/Slightly more full-fledged apps showcasing various features of the network.

Hope this helps
