 The core of FairMQ provides an abstract asynchronous message passing API with scalability protocols
 inspired by [ZeroMQ](https://github.com/zeromq/libzmq) (e.g. PUSH/PULL, PUB/SUB).
 FairMQ provides multiple implementations for its API (so-called "transports",
-e.g. `zeromq` and `shmem` (latest release of the `ofi` transport in v1.4.56, removed since v1.5+)) to cover
-a variety of use cases
+e.g. `zeromq`, `shmem` and `ofi` (in development)) to cover a variety of use cases
 (e.g. inter-thread, inter-process, inter-node communication) and machines (e.g. Ethernet, Infiniband).
 In addition to this core functionality FairMQ provides a framework for creating "devices" - actors which
-are communicating through message passing. FairMQ does not only allow the user to use different transport
-but also to mix them; i.e: A Device can communicate using different transport on different channels at the
-same time. Device execution is modelled as a simple state machine that shapes the integration points for
-the user task. Devices also incorporate a plugin system for runtime configuration and control.
-Next to the provided [devices](https://github.com/FairRootGroup/FairMQ/tree/master/fairmq/devices) and
-[plugins](https://github.com/FairRootGroup/FairMQ/tree/master/fairmq/plugins) the user can extend FairMQ

-
-```bash
-spack info fairmq # inspect build options
-spack install fairmq # build latest packaged version with default options

-Build FairMQ's dependencies via Spack for development:
-```bash
-git clone -b dev https://github.com/FairRootGroup/FairMQ fairmq_source
-spack --env fairmq_source install # installs deps declared in fairmq_source/spack.yaml
-spack env activate fairmq_source # sets $CMAKE_PREFIX_PATH which is used by CMake to find FairMQ's deps
-cmake -S fairmq_source -B fairmq_build -GNinja -DCMAKE_BUILD_TYPE=Debug -DBUILD_TESTING=ON
-# develop, compile, test
-spack env deactivate # at end of dev session, or simply close the shell
-```

 ## Usage

 FairMQ ships as a CMake package, so in your `CMakeLists.txt` you can discover it like this:

 ```cmake
-find_package(FairCMakeModules 1.0 REQUIRED)
+find_package(FairCMakeModules 0.2 REQUIRED)
 include(FairFindPackage2)
 find_package2(FairMQ)
 find_package2_implicit_dependencies()
@ -94,19 +68,31 @@ If FairMQ is not installed in system directories, you can hint the installation:
 list(PREPEND CMAKE_PREFIX_PATH /path/to/fairmq_install)
 ```

+Optionally, you can require certain FairMQ package components and a minimum version:
+
+```cmake
+find_package(FairMQ 1.4.0 COMPONENTS dds_plugin)
+```
+
+When building FairMQ, CMake will print a summary table of all available package components.

 For unit testing it is often not feasible to boot up a full-blown distributed system with dozens of processes.

-In some scenarios it is useful to not even instantiate a `fair::mq::Device` at all. Please see [this example](../test/protocols/_push_pull_multipart.cxx) for single and multi threaded unit test without a device instance. If you store your transport factories and channels on the heap, pls make sure, you destroy the channels before you destroy the related transport factory for proper shutdown. Channels provide all the `Send/Receive` and `New*Message/New*Poller` APIs provided by the device too.

-## 4.2 Static Analysis
-
-With `-DBUILD_TIDY_TOOL=ON` you can build the `fairmq-tidy` tool that implements static checks on your source code. To use it, enable the generation of a [compilation database](https://clang.llvm.org/docs/JSONCompilationDatabase.html) in your project via `-DCMAKE_EXPORT_COMPILE_COMMANDS=ON` (generates a file `<builddir>/compile_commands.json`):
-
-```
-fairmq-tidy -p <builddir> mysourcefile.cpp
-```
-
-If you find any issue (e.g. false positives) with this tool, please tell us by opening an issue on github.
-
-### 4.2.1 CMake Integration
-
-When discovering a FairMQ installation in your project, explicitely state, that you want one with the `fairmq-tidy` tool included:
-
-```
-find_package(FairMQ COMPONENTS tidy_tool)
-```
-
-Now the CMake module [`FairMQTidy.cmake`](../cmake/FairMQTidy.cmake) is available for inclusion:
-
-```
-include(FairMQTidy)
-```
-
-It provides the CMake function `fairmq_target_tidy()` which attaches appropriate `fairmq-tidy` build rules to each source file contained in the passed library or executable target, e.g. if you have an executable that uses FairMQ:
-
-```
-add_executable(myexe mysource1.cpp mysource2.cpp)
-target_link_libraries(myexe PRIVATE FairMQ::FairMQ)
-fairmq_target_tidy(TARGET myexe)
-```
-
-### 4.2.2 Extra Compiler Arguments
-
-On most Linux distros you are likely to use GCC to compile your projects, so the resulting `compile_commands.json` contains the command-line tuned for GCC which might be missing options needed to successfully invoke the Clang frontend which is used internally by `fairmq-tidy`. In general, you can pass extra `clang` options via the following options:
-
-```
-  --extra-arg=<string>        - Additional argument to append to the compiler command line
-  --extra-arg-before=<string> - Additional argument to prepend to the compiler command line
-```
-
-E.g. if standard headers are not found, you can hint the location like this:
-
-```
-fairmq-top -p <builddir> --extra-arg-before=-I$(clang -print-resource-dir)/include mysourcefile.cpp
-```

 ## 7.3 Provided Plugins

-### 7.3.1 PMIx
+### 7.3.1 DDS

-The [PMIx](https://pmix.org/) plugin enables launching a FairMQ topology with any PMIx capable launcher, e.g. the [Open Run-Time Environment (ORTE) of OpenMPI](https://www.open-mpi.org/doc/v4.0/man1/mpirun.1.php) or the [Slurm workload manager](https://slurm.schedmd.com/srun.html). This experimental plugin has been last released in v1.4.56 and is removed in v1.5+. For now there are no plans to pick up development of it again.
+When launching a FairMQ topology via [DDS](http://dds.gsi.de/) the DDS plugin enables FairMQ devices to interact with DDS' custom command and property subsystems - enable the plugin by passing `-P dds` on the command line.
+
+Via the property subsystem a FairMQ topology may exchange channel connection data (essentially to do service discovery) needed to connect/bind all FairMQ channels appropriately. DDS is highly optimized for this use case. See [examples/dds](examples/dds/README.md) for more details.
+
+Via the custom command subsystem a FairMQ device can receive a number of commands. FairMQ provides a convenient command line tool `fairmq-dds-command-ui` that allows interactive or scripted control of a running FairMQ topology managed via DDS. If one develops directly against the custom command DDS API, the following table lists all the commands the DDS plugin currently understands:
+
+| Custom Command | Response | Error | Description |
+| --- | --- | --- | --- |
+| `check-state` | `<ID>: <STATE> (pid: <PID>)` | n/a | Query current device state, see state machine for possible states |
+| `dump-config` | `(<ID>: <PKEY> -> <PVALUE>\n)+` | n/a | Query current device config (list property key/value pairs) |
+| `INIT DEVICE` | `<ID>: queued <CMD> transition` | `<ID>: could not queue <CMD> transition` | Initiate state transition |
+| `BIND` | `<ID>: queued <CMD> transition` | `<ID>: could not queue <CMD> transition` | Initiate state transition |

+| `RUN` | `<ID>: queued <CMD> transition` | `<ID>: could not queue <CMD> transition` | Initiate state transition |
+| `STOP` | `<ID>: queued <CMD> transition` | `<ID>: could not queue <CMD> transition` | Initiate state transition |
+| `RESET TASK` | `<ID>: queued <CMD> transition` | `<ID>: could not queue <CMD> transition` | Initiate state transition |
+| `RESET DEVICE` | `<ID>: queued <CMD> transition` | `<ID>: could not queue <CMD> transition` | Initiate state transition |
+| `END` | `<ID>: queued <CMD> transition` | `<ID>: could not queue <CMD> transition` | Initiate state transition |
+| `subscribe-to-heartbeats` | `heartbeat-subscription: <ID>,OK` | n/a | Subscribe to heartbeats |
+| on heartbeat subscription | `heartbeat: <ID>,<PID>` | n/a | Heartbeat every 100ms |

+# 8. Controller SDK
+
+The FairMQ Controller Software Development Kit (`-DBUILD_SDK=ON`) contains a (as of today still experimental) set of C++ APIs that provide essential functionality to the implementer of a global controller.
+
+The FairMQ core library only provides two local controllers - `static` (a fixed sequence of state transitions) and `interactive` (a read-eval-print-loop which reads keyboard commands from standard input). A local controller only knows how steer a single [FairMQ device](Device.md) - in fact, it runs in a thread within the device process.
+
+A global controller has knowledge about the full topology of connected FairMQ devices. Its responsibility is to facilitate the lifecycle of a distributed FairMQ-based application (*executing a topology*), such as
+
+* allocating/releasing compute resources from a resource management system,
+* launching/setting up the run-time environment and the FairMQ devices,
+* driving the device state machines in lock-step across the full topology,
+* pushing the device configuration,
+* monitoring (some aspects of the application's) operation,
+* and handling/reporting (some) error cases.
+
+The low-level hook to integrate FairMQ devices with such a global contoller is the [plugin mechanism](Plugins.md) in the FairMQ core library. The FairMQ Controller SDK provides C++ APIs that communicate to the endpoints exposed by such a FairMQ plugin.
+
+At the moment, the Controller SDK only supports [DDS](https://dds.gsi.de) as resource manager and run-time environment. A second implementation based on [PMIx](https://pmix.org/) (targeting its implementation in [Slurm](https://slurm.schedmd.com/documentation.html) and [OpenRTE](https://www-lb.open-mpi.org/papers/euro-pvmmpi-2005-orte/)) is in development.
+
+The following section give a short overview on the APIs provided.
+
+## RMS and run-time environment
+
+The classes [`fair::mq::sdk::DDSEnvironment`](../fairmq/sdk/DDSEnvironment.h), [`fair::mq::sdk::DDSSession`](../fairmq/sdk/DDSSession.h), and [`fair::mq::sdk::DDSTopology`](../fairmq/sdk/DDSTopology.h) are thin wrappers of most of the synchronous APIs exposed by DDS ([`dds::tools_api`](http://dds.gsi.de/doc/api-docs/DDS/html/namespacedds_1_1tools__api.html) and [`dds::topology_api`](http://dds.gsi.de/doc/api-docs/DDS/html/namespacedds_1_1topology__api.html)). E.g. they allow to [start a DDS session](https://github.com/FairRootGroup/FairMQ/blob/077eb0ef691940d764cfd1852bf3981dc812ddbd/main.cpp#L26-L28), [allocate resources](https://github.com/FairRootGroup/FairMQ/blob/077eb0ef691940d764cfd1852bf3981dc812ddbd/main.cpp#L34) and [launch a topology](https://github.com/FairRootGroup/FairMQ/blob/077eb0ef691940d764cfd1852bf3981dc812ddbd/main.cpp#L39) from a C++ program.
+
+## Driving the global state machine
+
+The class [`fair::mq::sdk::Topology`](../fairmq/sdk/Topology.h) adds a FairMQ-specific view on an existing DDS session that is executing a topology of FairMQ devices. One can e.g. [initiate a state transition on all devices in the topology simultaneously](https://github.com/FairRootGroup/FairMQ/blob/077eb0ef691940d764cfd1852bf3981dc812ddbd/main.cpp#L48-L49). This topology transition completes once a topology-wide barrier is passed (all devices completed the transition). This effectively exposes the device state machine as a topology state machine. The implementation is based on remote procedure calls over the [DDS intercom service](http://dds.gsi.de/doc/api-docs/DDS/html/namespacedds_1_1intercom__api.html) between the controller and the DDS plugin shipped with FairMQ (`-DBUILD_DDS_PLUGIN=ON`).
+
+For future versions of the SDK new APIs are planned to inspect and modify the device configurations and also operate only on subsets of a given topology.

 ```cpp
-fair::mq::MessagePtr NewMessage() const;

 **with no parameters**: Initializes an empty message (typically used for receiving).

 ```cpp
-fair::mq::MessagePtr NewMessage(const size_t size) const;

 ```cpp
 using fairmq_free_fn = void(void* data, void* hint);
-fair::mq::MessagePtr NewMessage(void* data, const size_t size, fairmq_free_fn* ffn, void* hint = nullptr) const;
+FairMQMessagePtr NewMessage(void* data, const size_t size, fairmq_free_fn* ffn, void* hint = nullptr) const;
 ```
 **given existing buffer and a size**: Initialize the message from an existing buffer. In case of ZeroMQ this is a zero-copy operation.

 Additionally, FairMQ provides two more message factories for convenience:
 ```cpp
 template<typename T>
-fair::mq::MessagePtr NewSimpleMessage(const T& data) const
+FairMQMessagePtr NewSimpleMessage(const T& data) const
 ```
 **copy and own**: Copy the `data` argument into the returned message and take ownership (free memory after message is sent). This interface is useful for small, [trivially copyable](http://en.cppreference.com/w/cpp/concept/TriviallyCopyable) data.

 ```cpp
 template<typename T>
-fair::mq::MessagePtr NewStaticMessage(const T& data) const
+FairMQMessagePtr NewStaticMessage(const T& data) const
 ```
 **point to existing memory**: The returned message will point to the `data` argument, but not take ownership (someone else must destruct this variable). Make sure that `data` lives long enough to be successfully sent. This interface is most useful for third party managed, contiguous memory (Be aware of shallow types with internal pointer references! These will not be sent.)

 ## 2.2 Channel

 A channel represents a communication endpoint in FairMQ. Usage is similar to a traditional Unix network socket. A device usually contains a number of channels that can either listen for incoming connections from channels of other devices or they can connect to other listening channels. Channels are organized by a channel name and a subchannel index.

 ```cpp
-const fair::mq::Channel& GetChannel(const std::string& channelName, const int index = 0) const;
