 # mini-recurrence-converter-dsl-dataset
 
-This dataset contains natural language recurrence expressions paired with symbolic DSL function calls, formatted in a structured `system → in → out` format. It is used for prototyping models that convert English recurrence descriptions (e.g., "every Tuesday at 8am") into structured, executable DSL representations.
+This dataset is used to prototype models for the [Mini Recurrence Converter DSL module](https://github.com/gh9869827/fifo-dev-dsl/tree/main/fifo_dev_dsl/domain_specific/mini_recurrence_converter_dsl).
+
+It pairs English **recurrence expressions** (e.g., `"every Tuesday at 8am"`) with symbolic DSL function calls (e.g., `WEEKLY(1, [TU], TIME(8, 0))`) compatible with the module.

 The dataset uses a **wide format** with the following three columns:
 
 - `system` — the system prompt that defines the model's task
-- `in` — the natural language recurrence string (e.g. `"every Tuesday at 8am"`)  
+- `in` — the natural language **recurrence expressions** (e.g. `"every Tuesday at 8am"`)  
 - `out` — the corresponding DSL expression (e.g. `WEEKLY(1, [TU], TIME(8, 0))`)
 
 Each entry consists of a `system`, `in`, and `out` field, forming a structured input-output example.

 ## ⚠️ Limitations
 
-This dataset does not cover all natural language recurrence phrasings or edge cases. It focuses on illustrative examples of common recurring schedule expressions. Users should evaluate and extend it as needed for their specific use case.
+This dataset is intended solely for prototyping models for the [Mini Recurrence Converter DSL module](https://github.com/gh9869827/fifo-dev-dsl/tree/main/fifo_dev_dsl/domain_specific/mini_recurrence_converter_dsl).

+It does not cover all phrasings or edge cases of English **recurrence expressions**. Instead, it focuses on illustrative examples supported by [the module's DSL functions](https://github.com/gh9869827/fifo-dev-dsl/tree/main/fifo_dev_dsl/domain_specific/mini_recurrence_converter_dsl#-dsl-syntax-and-examples). The dataset should be independently evaluated and extended to meet the specific requirements of any use case.
