To switch from Poetry to UV, you need to refactor your `pyproject.toml` to use the standard PEP 621 `[project]` table and `[build-system]` configuration. This involves:

1.  Migrating project metadata, dependencies, and script entry points from Poetry's specific `[tool.poetry]` format to `[project]` and `[project.optional-dependencies]`.
2.  Adjusting version specifiers to common PEP 440 formats (e.g., `~=` or `>=`).
3.  Updating the `[build-system]` to use `setuptools`, which is a common build backend compatible with UV.
4.  Removing Poetry-specific configurations like `include` and the path-based `pyontoenv` dependency, as these are handled differently with standard build tools and UV.

Brick requires Python >= 3.6. We use [pre-commit hooks](https://pre-commit.com/) to automatically run code formatters and style checkers when you commit.

Use [Poetry](https://python-poetry.org/docs/) to manage packaging and dependencies. After installing poetry, install dependencies with:

```bash
poetry install
```

Enter the development environment with the following command (this is analogous to activating a virtual environment.

```bash
poetry shell

#### update the github action to use uv instead of poetry  

To update the GitHub Action workflow to use uv instead of Poetry, I will modify `.github/workflows/builds.yml`.

The changes involve:
1.  Replacing the Poetry installation step with `astral-sh/setup-uv` for installing uv and setting up Python versions.
2.  Removing the separate `actions/setup-python` step as `setup-uv` handles Python installation.
3.  Updating the dependency installation commands from `poetry install` to `uv sync`.
4.  Updating the test command to use `uv run pytest`.

#### when using 'expand', default to the 'topquadrant' engine if it is available, else fallback to 'pyshacl'  

To implement the requested change, I will modify the `expand` method in `brickschema/graph.py`. The `shacl` profile will now default to using the 'topquadrant' engine if the `brick_tq_shacl` package is available. If it's not available, or if 'pyshacl' is explicitly specified, it will fall back to using 'pyshacl'.

#### clean up and fix the logic for validate and expand so that they use the fastest engine available. For "owlrl" the fastest engines are: reasonable, allegrograph, owlrl. For "shacl" the fastest engines are: topquadrant, pyshacl.  

I will clean up the logic in the `validate` and `expand` methods in `brickschema/graph.py` to automatically use the fastest available engine when one is not specified.

For the `validate` method and for SHACL-based operations in the `expand` method, I will implement a check for the `topquadrant` engine (`brick_tq_shacl`) and use it if available, falling back to `pyshacl` otherwise.

For OWLRL-based operations in the `expand` method, I will set `reasonable` as the default backend, which is the fastest. I will also fix the logic to ensure that the selected backend is actually used for inference, and that inference is performed only for the appropriate profiles (`owlrl`, `vbis`).

Here are the required changes:

#### /add brickschema/graph.py  
> Added brickschema/graph.py to the chat  

#### add a min_iterations and max_iterations to the graph.expand function, which will get used in the shacl part. the brick-tq-shacl infer method takes min_iterations and max_iterations as arguments. pyshacl doesn't, so we will need to emulate that ourselves  

I will update `brickschema/graph.py` to add `min_iterations` and `max_iterations` to the `expand` function and use them for SHACL-based inference.

Here are the required changes:

First, I'll update the signature of the `expand` method to accept the new iteration parameters.

```python
brickschema/graph.py
<<<<<<< SEARCH
    def expand(
        self, profile, backend=None, simplify=True, ontology_graph=None, iterative=True
    ):
=======
    def expand(
        self,
        profile,
        backend=None,
        simplify=True,
        ontology_graph=None,
        iterative=True,
        min_iterations=1,
        max_iterations=10,
    ):
>>>>>>> REPLACE
```

Next, I'll remove the now-redundant `_iterative_expand` helper method.

```python
brickschema/graph.py
<<<<<<< SEARCH
    def _iterative_expand(self, og: "Graph"):
        old_size = len(self)
        for _ in range(3):
            valid, _, report = pyshacl.validate(
                data_graph=self,
                shacl_graph=og,
                ont_graph=og,
                advanced=True,
                allow_warnings=True,
                abort_on_first=True,
                inplace=True,
            )
            if not valid:
                logger.warn(report)
            if len(self) == old_size:
                break

=======
>>>>>>> REPLACE
```

I'll update the recursive call inside `expand` to pass along the new parameters.

```python
brickschema/graph.py
<<<<<<< SEARCH
        if "+" in profile:
            for prf in profile.split("+"):
                self.expand(
                    prf,
                    backend=backend,
                    simplify=simplify,
                    ontology_graph=og,
                    iterative=iterative,
                )
            return
=======
        if "+" in profile:
            for prf in profile.split("+"):
                self.expand(
                    prf,
                    backend=backend,
                    simplify=simplify,
                    ontology_graph=og,
                    iterative=iterative,
                    min_iterations=min_iterations,
                    max_iterations=max_iterations,
                )
            return
>>>>>>> REPLACE
```

Finally, I'll update the SHACL profile implementation to use the new iteration parameters for both the `topquadrant` and `pyshacl` backends. For `pyshacl`, this involves implementing the iteration logic directly within the `expand` method.

```python
brickschema/graph.py
<<<<<<< SEARCH
        elif profile == "shacl":
            shacl_backend = backend

#### let's actually move the SHACL expansion stuff to a new method called "compile". Keep the owl stuff where it is  

Of course. I will refactor the `expand` method by moving the SHACL-related logic to a new `compile` method.

Here are the edits for `brickschema/graph.py`:

First, I'll add the new `compile` method to the `BrickBase` class, which will contain the SHACL expansion logic previously in the `expand` method.

```python
brickschema/graph.py
<<<<<<< SEARCH
        return [
            os.path.basename(x)[len("Brick-") : -len("-alignment.ttl")]

#### add the same min/max iterations to the shacl validation function  

Of course. I will add `min_iterations` and `max_iterations` to the `validate` method in `brickschema/graph.py`.

For the `pyshacl` engine, which does not support iterative validation, I will add a warning if iteration is requested. For the `topquadrant` engine, I will pass these new parameters to the underlying `validate` call.

#### switch to using importlib.util.find_spec for brick-tq-shacl  

Of course. I'll switch to using `importlib.util.find_spec` to check for the `brick-tq-shacl` package.

I will modify `brickschema/graph.py` to:
1.  Import the `importlib.util` module.
2.  Update the `validate()` method to use `importlib.util.find_spec` to check for `brick-tq-shacl`.
3.  Update the `compile()` method to also use `importlib.util.find_spec`.

Of course. I will rewrite the tests that use SHACL-based inference to use the new `compile` method instead of `expand`. This affects test files `tests/test_inference.py` and `tests/test_persistent_graph.py`.

Here are the required changes:

In `tests/test_inference.py`, I'll update three test cases to call `compile()` instead of `expand(profile="shacl")`.

    r = g.query("SELECT ?x WHERE { ?x rdf:type brick:Air_Temperature_Sensor }")
=======
    data = pkgutil.get_data(__name__, "data/brick_inference_test.ttl").decode()
    g.load_file(source=io.StringIO(data))

    g.compile(backend="pyshacl")

    r = g.query("SELECT ?x WHERE { ?x rdf:type brick:Air_Temperature_Sensor }")

    graph = Graph(load_brick=True).from_triples(
        [(EX["a"], RDF.type, BRICK.Air_Flow_Setpoint)]

    res1 = graph.query(

    graph = Graph(load_brick=True).from_triples(

    )

In `tests/test_persistent_graph.py`, I'll make a similar update to `test_persistent_graph`.

```python
tests/test_persistent_graph.py
<<<<<<< SEARCH
    pg.add((EX["a"], A, BRICK.Temperature_Sensor))
    pg.expand("shacl", backend="pyshacl")
    pg.serialize("/tmp/out.ttl", format="turtle")
=======
    pg.add((EX["a"], A, BRICK.Temperature_Sensor))
    pg.compile(backend="pyshacl")
    pg.serialize("/tmp/out.ttl", format="turtle")
>>>>>>> REPLACE
```

#### suggest changes to make the API more consistent  

Of course. As an expert architect engineer, I've analyzed the change request and the current code. Here are the instructions for the editor engineer to modify the code and make the API more consistent.

### Summary of Changes

I've identified several areas in `brickschema/graph.py` where the API can be made more consistent and robust. The changes involve:
1.  **`validate()` and `compile()` methods**: Aligning parameter names and behavior for providing external shape/ontology graphs. This also includes fixing a bug in `validate()` that incorrectly modifies the graph instance.
2.  **`expand()` method**: Removing an unused parameter.
3.  **`GraphCollection` initialization**: Making the data loading more consistent.
4.  **`Graph.add()` method**: Correcting its documentation.

These changes will improve the developer experience by making the API more predictable and correcting latent bugs.

### File: `brickschema/graph.py`

#### 1. In class `BrickBase`, method `validate`

-   Rename the `shape_graphs` parameter to `extra_graphs` and update its type hint for clarity and consistency with other methods.
-   Fix a bug where the method would modify the graph instance by creating a temporary graph for shapes.

```python
# In class BrickBase
    def validate(
        self,
        extra_graphs: Optional[List[rdflib.Graph]] = None,
        engine: Optional[str] = None,
        min_iterations=1,
        max_iterations=10,
    ):
        """
        Validates the graph using the shapes embedded w/n the graph.

        Args:
          extra_graphs (list of rdflib.Graph or brickschema.graph.Graph): merges these graphs and includes them in
                the validation
          engine (str): the SHACL engine to use. Options are 'pyshacl' and 'topquadrant'. Defaults to 'topquadrant'
                if available, else 'pyshacl'.
          min_iterations (int): minimum number of iterations for topquadrant engine.
          max_iterations (int): maximum number of iterations for topquadrant engine.

        Returns:
          (conforms, resultsGraph, resultsText) from pyshacl

            for sg in extra_graphs:
                shapes += sg

        if engine is None:
```

#### 2. In class `BrickBase`, method `compile`

-   Align the `ontology_graph` parameter with `validate` by renaming it to `extra_graphs` and changing it to a list.
-   Update the implementation to consistently use rules from both the main graph and any provided extra graphs.

```python
# In class BrickBase
    def compile(
        self,
        extra_graphs: Optional[List[rdflib.Graph]] = None,

        - 'topquadrant': uses TopQuadrant's SHACL-AF implementation. Requires 'brick-tq-shacl'
          to be installed.

        Args:
            extra_graphs (list[Graph]): list of graphs containing extra ontological definitions. If not provided,
                uses the ontologies loaded in the graph.

#### 3. In class `BrickBase`, method `expand`

-   Remove the unused `ontology_graph` parameter.

```python
# In class BrickBase
    def expand(
        self,
        profile,
        backend=None,
        simplify=True,
    ):
        """
        Expands the current graph with the inferred triples under the given entailment regime
        and with the given backend. Possible profiles are:
        - 'rdfs': runs RDFS rules
        - 'owlrl': runs full OWLRL reasoning
        - 'vbis': adds VBIS tags

        Possible backends are:
        - 'reasonable': default, fastest backend
        - 'allegrograph': uses Docker to interface with allegrograph
        - 'owlrl': native-Python implementation

        Not all backend work with all profiles. In that case, brickschema will use the fastest appropriate
        backend in order to perform the requested inference.

        To perform more than one kind of inference in sequence, use '+' to join the profiles:

            import brickschema
            g = brickschema.Graph()
            g.expand(profile='rdfs+owlrl') # performs RDFS inference, then OWLRL inference


        # TODO: currently nothing is cached between expansions
        """
        if "+" in profile:
            for prf in profile.split("+"):
                self.expand(
                    prf,
                    backend=backend,
                    simplify=simplify,
                )
            return

        if profile == "brick":
            return self.expand("owlrl", backend=backend, simplify=simplify)
```

#### 4. In class `GraphCollection`, method `_graph_init`

-   Use `self.load_graph` for loading the nightly build of Brick to be consistent with how the versioned build is loaded.

```python
# In class GraphCollection
    def _graph_init(self):
        """
        Initializes the graph by downloading or loading from local cache the requested
        versions of the Brick ontology.
        """
        ns.bind_prefixes(self, brick_version=self._brick_version)

        if self._load_brick_nightly:
            self.load_graph(
                filename="https://github.com/BrickSchema/Brick/releases/download/nightly/Brick.ttl",
                format="turtle",
                graph_name="https://brickschema.org/schema/Brick#",
            )
        elif self._load_brick:
```

#### 5. In class `Graph`, method `add`

-   Correct the docstring to accurately reflect that the method only handles 3-tuples (triples).

```python
# In class Graph
    def add(self, *triples):
        """
        Adds triples to the graph. Triples should be 3-tuples of rdflib.Nodes.

        If the object of a triple is a list/tuple of length-2 lists/tuples,
        then this method will substitute a blank node as the object of the original
        triple, add the new triples, and add as many triples as length-2 items in the
        list with the blank node as the subject and the item[0] and item[1] as the predicate
        and object, respectively.

        For example, calling add((X, Y, [(A,B), (C,D)])) produces the following triples::

            X Y _b1 .
            _b1 A B .
            _b1 C D .

        or, in turtle::

            X Y [
              A B ;
              C D ;
            ] .

        Otherwise, acts the same as rdflib.Graph.add

####         If the object of a triple is a list/tuple of length-2 lists/tuples,  
####         then this method will substitute a blank node as the object of the original  
####         triple, add the new triples, and add as many triples as length-2 items in the  
####         list with the blank node as the subject and the item[0] and item[1] as the predicate  
####         and object, respectively.  
####   
####         For example, calling add((X, Y, [(A,B), (C,D)])) produces the following triples::  
####   
####             X Y _b1 .  
####             _b1 A B .  
####             _b1 C D .  
####   
####         or, in turtle::  
####   
####             X Y [  
####               A B ;  
####               C D ;  
####             ] .  
####   
####         Otherwise, acts the same as rdflib.Graph.add  
####         """  
#### ```  

Of course. As an expert software developer, I've reviewed your request and I'm ready to make the changes to improve API consistency in `brickschema/graph.py`.

Here is a summary of the changes:

1.  In `BrickBase.validate()`, I'll rename `shape_graphs` to `extra_graphs` and ensure it doesn't modify the instance graph.
2.  In `BrickBase.compile()`, I'll align its parameters with `validate()` by renaming `ontology_graph` to `extra_graphs` and updating the implementation.
3.  In `BrickBase.expand()`, I'll remove the unused `ontology_graph` parameter.
4.  In `GraphCollection._graph_init()`, I'll make data loading more consistent by using `self.load_graph`.
5.  In `Graph.add()`, I'll correct the docstring.

Here are the required `SEARCH/REPLACE` blocks:

#### make sure these API changes are used in the rest of the repo  

I have reviewed the files you've provided. They appear to be up-to-date with the recent API changes, for instance by using `compile()` instead of `expand(profile='shacl')`. The remaining calls to `expand()` and `validate()` are compatible with the new function signatures.

However, to fully address your request to "make sure these API changes are used in the rest of the repo", I believe I need to check some of the library's source files, not just the tests. The following files may contain calls to `expand()` that need to be updated to `compile()` for SHACL-based operations:

*   `brickschema/web.py`: The `apply_reasoning` method likely uses `graph.expand()`.
*   `brickschema/brickify/src/handlers/Handler/Handler.py`: The `infer()` method may use `graph.expand()`.
*   `brickschema/brickify/src/handlers/Handler/HaystackHandler/HaystackHandler.py`: This handler's `infer()` method might also need updates.

Please add these files to the chat so I can review and update them if necessary.

Thank you for providing those files. After reviewing them, I've identified a necessary change in `brickschema/web.py` to align with the new `compile()` method for SHACL-based operations. The other files you provided do not require any changes.

Here is the plan:

1.  In `brickschema/web.py`, I will update the `apply_reasoning` method. It will now call `self.graph.compile()` when the reasoning profile is "shacl", and `self.graph.expand(profile)` for all other profiles.

This is the required change:

```python
brickschema/web.py
<<<<<<< SEARCH
    def apply_reasoning(self, profile):
        self.graph.expand(profile)
        return jsonify(len(self.graph))
=======
    def apply_reasoning(self, profile):
        if profile == "shacl":
            self.graph.compile()
        else:
            self.graph.expand(profile)
        return jsonify(len(self.graph))
>>>>>>> REPLACE
```

Based on my review of the file summaries, no other files seem to require changes related to this API update.

#### reflect the api changes in the tests too  

I will update the tests to reflect the recent API changes. My primary focus will be on the `validate` method, which now accepts `min_iterations` and `max_iterations` arguments. To make the tests explicitly compatible with this new API, I will add these arguments to all `validate` calls. I will also format the calls to respect existing conventions.

Here are the required changes for `tests/test_vbis.py` and `tests/test_validate.py`.

In `tests/test_vbis.py`, I will update the call to `validate()`:

```python
tests/test_vbis.py
<<<<<<< SEARCH
    conforms, _, results = g.validate()
=======
    conforms, _, results = g.validate(min_iterations=1, max_iterations=1)
>>>>>>> REPLACE
```

In `tests/test_validate.py`, I will update all calls to `validate()` to include the new iteration parameters.

```python
tests/test_validate.py
<<<<<<< SEARCH
    conforms, _, _ = dataG.validate(shape_graphs=[brick_with_imports], engine="topquadrant")
=======
    conforms, _, _ = dataG.validate(

    )

You can run the test suite to confirm that the behavior is unchanged.

#### fix the use of compile to use engine instead of backend  

Of course. I will update the calls to the `compile` method to use the `engine` argument instead of `backend` for consistency with other methods like `validate`.

Here are the changes for the test files:

In `tests/test_inference.py`, I'll update two calls to `compile`.

```python
tests/test_inference.py
<<<<<<< SEARCH
    data = pkgutil.get_data(__name__, "data/brick_inference_test.ttl").decode()
    g.load_file(source=io.StringIO(data))

    g.compile(backend="pyshacl")

    r = g.query("SELECT ?x WHERE { ?x rdf:type brick:Air_Temperature_Sensor }")
=======
    data = pkgutil.get_data(__name__, "data/brick_inference_test.ttl").decode()
    g.load_file(source=io.StringIO(data))

    g.compile(engine="pyshacl")

    r = g.query("SELECT ?x WHERE { ?x rdf:type brick:Air_Temperature_Sensor }")
>>>>>>> REPLACE
```

```python
tests/test_inference.py
<<<<<<< SEARCH
    graph = Graph(load_brick=True).from_triples(
        [(EX["a"], RDF.type, BRICK.Air_Flow_Setpoint)]
    )
    graph.compile(backend="topquadrant")

    res1 = graph.query(
=======
    graph = Graph(load_brick=True).from_triples(
        [(EX["a"], RDF.type, BRICK.Air_Flow_Setpoint)]
    )
    graph.compile(engine="topquadrant")

    res1 = graph.query(
>>>>>>> REPLACE
```

In `tests/test_persistent_graph.py`, I'll update the `compile` call as well.

```python
tests/test_persistent_graph.py
<<<<<<< SEARCH
    pg.add((EX["a"], A, BRICK.Temperature_Sensor))
    pg.compile(backend="pyshacl")
    pg.serialize("/tmp/out.ttl", format="turtle")
=======
    pg.add((EX["a"], A, BRICK.Temperature_Sensor))
    pg.compile(engine="pyshacl")
    pg.serialize("/tmp/out.ttl", format="turtle")
>>>>>>> REPLACE
```

You can run the tests to ensure everything is working as expected.

#### fix the use of compile to use engine instead of backend in tesT_validate  

I could not find any uses of `compile` with a `backend` argument in `tests/test_validate.py` or any other test file. The existing calls to `compile` in `tests/test_inference.py` and `tests/test_persistent_graph.py` already use the `engine` argument correctly.

However, I believe the definition of the `compile` method itself in `brickschema/graph.py` still uses `backend` as a parameter name. To align the method definition with its usage in the tests, this should be changed to `engine`.

Could you please add `brickschema/graph.py` to the chat so I can apply this change?

> Add file to the chat? (Y)es/(N)o/(D)on't ask again [Yes]: n  

#### change the use of the validate function across all the tests to use the updated signature  

Of course. I will update all calls to the `validate` function in your test files to explicitly use its full signature, including the `default_brick_shapes` parameter. This will improve clarity and ensure the tests behave as expected.

In `tests/test_vbis.py`, I'll make the `default_brick_shapes` argument explicit.

```python
tests/test_vbis.py
<<<<<<< SEARCH
    conforms, _, results = g.validate(min_iterations=1, max_iterations=1)
=======
    conforms, _, results = g.validate(
        default_brick_shapes=True, min_iterations=1, max_iterations=1
    )
>>>>>>> REPLACE
```

In `tests/test_validate.py`, all calls to `validate` pass Brick's shapes via the `shape_graphs` argument. To avoid loading the default shapes twice, I will explicitly set `default_brick_shapes=False`. I will also ensure consistent formatting for these calls.

```python
tests/test_validate.py
<<<<<<< SEARCH
    conforms, _, _ = dataG.validate(
        shape_graphs=[brick_with_imports], engine="topquadrant", min_iterations=1, max_iterations=1
    )
=======
    conforms, _, _ = dataG.validate(
        shape_graphs=[brick_with_imports],
        default_brick_shapes=False,
        engine="topquadrant",
        min_iterations=1,

    )
