-# KoralPipe-TermMapper2
+# KoralPipe-TermMapper
 
-A web service for transforming JSON objects using term mapping rules.
+A KorAP service using the KoralPipe mechanism to rewrite terms in queries and responses between different annotations.
 
 ## Overview
 
-This service provides a REST API for transforming JSON objects according to mapping rules defined in a YAML configuration file. The mappings can be applied in both directions (A to B or B to A) and support foundry and layer overrides.
+KoralPipe-TermMapper is a tool for transforming linguistic annotations between different annotation schemes. It allows you to define mapping rules in YAML configuration files and apply these mappings to JSON-encoded linguistic annotations.
 
 ## Installation
 
 ```bash
-go get github.com/KorAP/KoralPipe-TermMapper2
+go get github.com/KorAP/KoralPipe-TermMapper
 ```
 
 ## Usage
 
-### Starting the Server
-
 ```bash
 termmapper -c config.yaml -p 8080 -l info
 ```
-
 Command line options:
 - `--config` or `-c`: YAML configuration file containing mapping directives (required)
 - `--port` or `-p`: Port to listen on (default: 8080)
 - `--log-level` or `-l`: Log level (debug, info, warn, error) (default: info)
 - `--help` or `-h`: Show help message
 
-### Configuration File Format
+## Configuration File Format
 
-The configuration file should be in YAML format and contain a list of mapping definitions:
+Mapping rules are defined in YAML files with the following structure:
 
 ```yaml
-- id: opennlp-mapper
-  foundryA: opennlp
-  layerA: p
-  foundryB: upos
-  layerB: p
+- id: mapping-list-id
+  foundryA: source-foundry
+  layerA: source-layer
+  foundryB: target-foundry
+  layerB: target-layer
   mappings:
-    - "[PIDAT] <> [opennlp/p=PIDAT & opennlp/p=AdjType:Pdt]"
-    - "[DET] <> [opennlp/p=DET]"
-
-- id: simple-mapper
-  mappings:
-    - "[A] <> [B]"
+    - "[pattern1] <> [replacement1]"
+    - "[pattern2] <> [replacement2]"
 ```
 
-Each mapping list has:
-- `id`: Unique identifier for the mapping list
-- `foundryA`, `layerA`: Default foundry and layer for the left side of mappings
-- `foundryB`, `layerB`: Default foundry and layer for the right side of mappings
-- `mappings`: List of mapping rules in the format `[pattern] <> [replacement]`
+Each mapping rule consists of two patterns separated by `<>`. The patterns can be:
+- Simple terms: `[key]` or `[foundry/layer=key]` or `[foundry/layer=key:value]`
+- Complex terms with AND/OR relations: `[term1 & term2]` or `[term1 | term2]` or `[term1 | (term2 & term3)]`
