# AtomSpace Server This is a simple project that provides Websockets access to the OpenCog [AtomSpace](https://github.com/opencog /atomspace ) to execute pattern matching queries. It also allows users to create multiple atomspaces and access them separately. Users can use a JSON config file to specify the id and the directory containing the atomese code to load. An example config looks like the following: ```json [ { "id": "asp1", "pathDir": "/path/to/atomese/code/" }, { "id": "asp2", "pathDir": "/path/to/another/atomese/code" } ] ``` You can use the above JSON to start the server like this: $ atom_server --config /path/to/setting.json This will create to AtomSpaces with ids`asp1` & `asp2` and can be accessed via WebSockets. An example Javascript to access an AtomSpace containing the `sample_dataset.scm` can be: ```html

``` ### Building and Installation #### 1. Requirements: This project depends on the following libraries: - [AtomSpace](https://github.com/opencog/atomspace) - [Boost](https://www.boost.org/) - [uWebSockets](https://github.com/uNetworking/uWebSockets) -- make sure you check out the `v18` branch * Note: [uSockets](https://github.com/uNetworking/uSockets) library is needed which uWebSockets depends on it. After building the uSockets, you need to copy the static library to a library search path (e.g /usr/local/lib) - [nlohmann_json](https://github.com/nlohmann/json) - [Agi-bio](https://github.com/opencog/agi-bio) - this is OPTIONAL and will be required if you are working with bio related atomspace #### 2. Building ```bash $ cd atomspace_server $ mkdir build && cd build $ cmake .. $ make $ make install ``` ### Note This project is inspired by the already existing [CogServer](https://github.com/opencog/cogserver). However , this project is intended provide to a very simple, high-level access to the AtomSpace to run pattern matching queries via Websockets and the ability to load multiple atomspaces at once. It doesn't support the use Scheme or Python REPL to access an AtomSpace and you can't do anything complex(yet) such as job monitoring, loading other scheme modules ..etc that you can do with CogServer. If you are looking for such functionality please check out CogServer.
