# Fabric
[](https://godoc.org/github.com/spy16/fabric) [](https://goreportcard.com/report/github.com/spy16/fabric)
Fabric is a triple-store written in `Go`. Fabric provides simple functions
and store options to deal with "Subject->Predicate->Object" relations or so called
triples.
## Usage
Get fabric by using `go get -u github.com/spy16/fabric` (Fabric as a library has no
external dependencies)
```go
// See next snippet for using persistent SQL backend
fab := fabric.New(&fabric.InMemoryStore{})
fab.Insert(context.Background(), fabric.Triple{
Source: "Bob",
Predicate: "Knows",
Target: "John",
})
fab.Query(context.Background(), fabric.Query{
Source: fabric.Clause{
Type: "equal",
Value: "Bob",
},
})
```
To use a SQL database for storing the triples, use the following snippet:
```go
db, err := sql.Open("sqlite3", "fabric.db")
if err != nil {
panic(err)
}
store := &fabric.SQLStore{DB: db}
store.Setup(context.Background()) // to create required tables
fab := fabric.New(store)
```
> Fabric `SQLStore` uses Go's standard `database/sql` package. So any SQL database
> supported through this interface (includes most major SQL databases) should work.
Additional store support can be added by implementing the `Store` interface.
```go
type Store interface {
Insert(ctx context.Context, tri Triple) error
Query(ctx context.Context, q Query) ([]Triple, error)
Delete(ctx context.Context, q Query) (int, error)
}
```
Optional `Counter` and `ReWeighter` can be implemented by the store implementations
to support extended query options.
## REST API
The `server` package exposes REST APIs (`/triples` endpoint) which can be used to query,
insert/delete or reweight triples using any HTTP client.
