# IggyAPI - IGGY: Your IG Spirit Animal
|
||
Knows every guide inside out, and helps you fetch, explore, and use them.
|
||
|
||
|
||
IggyAPI is a FastAPI-based application designed to search, retrieve, and manage FHIR Implementation Guides (IGs) and their associated StructureDefinitions (profiles). It offers a powerful interface for querying FHIR packages, listing profiles within an IG, and fetching specific StructureDefinitions with the option to strip narrative content. Tailored to support healthcare interoperability in an Australian context, IggyAPI is capable of handling IGs from various FHIR registries worldwide.

## Project Overview
|
||
|
||
IggyAPI is a backend service that enables developers and healthcare systems to interact with FHIR Implementation Guides programmatically. It retrieves metadata from FHIR registries, caches the data, and provides endpoints to search for IGs, list profiles within an IG, and fetch specific StructureDefinitions. A key feature of IggyAPI is its support for narrative stripping in StructureDefinitions, which helps reduce payload size when human-readable content is not required.
|
||
|
||
While IggyAPI is particularly focused on supporting AU Core profiles (e.g., `hl7.fhir.au.core`), it is designed to work with any FHIR IG published in supported registries, such as `packages.fhir.org` and `packages.simplifier.net`.
|
||
|
||
## Features
|
||
|
||
- **Search IGs**: Query Implementation Guides using a search term with semantic or string similarity matching.
|
||
- **List Profiles**: Retrieve a list of StructureDefinitions (profiles) within a specified IG, with optional version filtering.
|
||
- **Fetch Profiles**: Obtain a specific StructureDefinition by IG and profile ID, with an option to exclude narrative content.
|
||
- **Cache Management**: Automatically syncs IG metadata from registries every 8 hours or on demand, with status reporting.
|
||
- **Robust Error Handling**: Provides detailed error messages for invalid requests or unavailable resources.
|
||
- **Swagger UI**: Offers an interactive API documentation interface at `/docs`.
|
||
|
||
## Prerequisites
|
||
|
||
Before setting up IggyAPI, ensure you have the following installed:
|
||
|
||
- **Python 3.8+**: IggyAPI is built using Python.
|
||
- **pip**: Python package manager for installing dependencies.
|
||
- **SQLite**: Used for caching (included with Python).
|
||
- **Git**: For cloning the repository (optional).
|
||
- **Docker**: Required for running IggyAPI in a container.
|
||
- **SpaCy Model**: IggyAPI uses SpaCy for advanced search functionality, requiring the `en_core_web_md` model for semantic similarity searches.
|
||
|
||
An internet connection is required to fetch IG metadata from FHIR registries during the initial sync.
|
||
|
||
## Installation
|
||
|
||
1. **Clone the Repository** (if applicable):
|
||
```bash
|
||
git clone <repository-url>
|
||
cd iggyapi
|
||
```
|
||
|
||
2. **Create a Virtual Environment** (recommended for non-Docker setup):
|
||
```bash
|
||
python -m venv venv
|
||
source venv/bin/activate # On Windows: venv\Scripts\activate
|
||
```
|
||
|
||
3. **Install Dependencies** (for non-Docker setup):
|
||
IggyAPI requires several Python packages listed in `requirements.txt`. Install them using:
|
||
```bash
|
||
pip install -r requirements.txt
|
||
```
|
||
Example `requirements.txt`:
|
||
```
|
||
fastapi==0.115.0
|
||
uvicorn==0.30.6
|
||
requests==2.32.3
|
||
feedparser==6.0.11
|
||
sqlalchemy==2.0.35
|
||
tenacity==9.0.0
|
||
rapidfuzz==3.10.0
|
||
spacy==3.7.6
|
||
en-core-web-md @ https://github.com/explosion/spacy-models/releases/download/en_core_web_md-3.7.1/en_core_web_md-3.7.1-py3-none-any.whl
|
||
```
|
||
|
||
4. **Verify Setup** (for non-Docker setup):
|
||
Ensure all dependencies are installed by running:
|
||
```bash
|
||
pip list
|
||
```
|
||
Confirm that `fastapi`, `uvicorn`, `requests`, `sqlalchemy`, `spacy`, and other required packages are listed.
|
||
|
||
5. **Verify SpaCy Model** (for non-Docker setup):
|
||
Confirm that the SpaCy model is installed by running:
|
||
```bash
|
||
python -m spacy validate
|
||
```
|
||
You should see `en_core_web_md` listed as installed. If not, ensure the model was downloaded correctly via the `requirements.txt` installation.
|
||
|
||
## Running IggyAPI
|
||
|
||
1. **Start the Server** (for non-Docker setup):
|
||
Launch IggyAPI using `uvicorn`:
|
||
```bash
|
||
uvicorn main:app --host 0.0.0.0 --port 8000
|
||
```
|
||
- `--host 0.0.0.0`: Allows external access to the API.
|
||
- `--port 8000`: The port to listen on (default is 8000; adjust as needed).
|
||
|
||
2. **Access IggyAPI**:
|
||
- Open your browser and navigate to `http://localhost:8000/docs` to access the Swagger UI.
|
||
- The Swagger UI provides an interactive interface to test IggyAPI’s endpoints.
|
||
|
||
3. **Initial Sync and Scheduled Refreshes**:
|
||
On startup, IggyAPI will load any existing data from the database into memory, even if it’s older than 8 hours. If the data is older than 8 hours or missing, a background refresh will be triggered to fetch the latest IG metadata from FHIR registries. This process may take a few minutes depending on your internet connection. After the initial refresh, IggyAPI schedules automatic refreshes every 8 hours from the last refresh time (whether triggered at startup, in the background, or manually via the `/refresh-cache` endpoint). You can also trigger a manual refresh at any time using the `/refresh-cache` endpoint.
|
||
|
||
## Build the Docker Image
|
||
|
||
Ensure you are in the project directory where the `Dockerfile` is located. Build the Docker image using:
|
||
```bash
|
||
docker build -t iggyapi:latest .
|
||
```
|
||
This creates an image named `iggyapi` with the `latest` tag. Optionally, you can add a `--name iggyapi-container` flag during the run step to name the container for easier reference.
|
||
|
||
## Run the Docker Container
|
||
|
||
Start a container from the built image, mapping port 8000 on your host to port 8000 in the container:
|
||
```bash
|
||
docker run -d -p 8000:8000 -e PORT=8000 -v C:/git/IggyApi/instance:/app/instance --name iggyapi-container iggyapi:latest
|
||
```
|
||
|
||
**Verify the Container is Running**:
|
||
Check the status of the container:
|
||
```bash
|
||
docker ps
|
||
```
|
||
You should see `iggyapi-container` listed as running.
|
||
|
||
**Initial Sync and Scheduled Refreshes**:
|
||
On startup, IggyAPI will load any existing data from the database into memory, even if it’s older than 8 hours. If the data is older than 8 hours or missing, a background refresh will be triggered to fetch the latest IG metadata from FHIR registries. This process may take a few minutes depending on your internet connection. After the initial refresh, IggyAPI schedules automatic refreshes every 8 hours from the last refresh time (whether triggered at startup, in the background, or manually via the `/refresh-cache` endpoint). You can also trigger a manual refresh at any time using the `/refresh-cache` endpoint.
|
||
|
||
## API Endpoints
|
||
|
||
IggyAPI provides the following endpoints, all documented in the Swagger UI at `/docs`.
|
||
|
||
### Search Implementation Guides
|
||
|
||
- **Endpoint**: `GET /igs/search`
|
||
- **Query Parameters**:
|
||
- `query` (string, optional): A search term to filter IGs by name or author (e.g., `au core`).
|
||
- `search_type` (string, optional, default: `semantic`): The type of search to perform. Options are:
|
||
- `semantic`: Uses SpaCy for semantic similarity, matching based on the meaning of the query and package metadata. If the semantic similarity is low, it falls back to rapidfuzz for string-based matching.
|
||
- `string`: Uses SpaCy for token-based string similarity, with a fallback to rapidfuzz for exact or near-exact string matching.
|
||
- **Description**: Searches for FHIR Implementation Guides using either semantic or string similarity matching. The search first filters packages by ensuring all words in the query are present in the package name or author, then applies the specified similarity search on the filtered results. Returns a list of matching IGs with metadata such as version, FHIR version, and relevance score.
|
||
- **Response**: A JSON object containing a list of IGs, total count, and cache status.
|
||
|
||
### List Profiles in an IG
|
||
|
||
- **Endpoint**: `GET /igs/{ig_id}/profiles`
|
||
- **Path Parameter**:
|
||
- `ig_id` (string, required): The ID of the IG (e.g., `hl7.fhir.au.core` or `hl7.fhir.au.core#1.1.0-preview`).
|
||
- **Query Parameter**:
|
||
- `version` (string, optional): The version of the IG (e.g., `1.1.0-preview`). Overrides the version in `ig_id` if provided.
|
||
- **Description**: Lists all StructureDefinitions (profiles) within the specified IG. Downloads the IG package if not already cached and extracts profile metadata.
|
||
- **Response**: A list of profiles with their name, description, version, and URL.
|
||
|
||
### Get a Specific Profile
|
||
|
||
- **Endpoint**: `GET /igs/{ig_id}/profiles/{profile_id}`
|
||
- **Path Parameters**:
|
||
- `ig_id` (string, required): The ID of the IG (e.g., `hl7.fhir.au.core`).
|
||
- `profile_id` (string, required): The ID or name of the profile (e.g., `AUCorePatient`).
|
||
- **Query Parameters**:
|
||
- `version` (string, optional): The version of the IG (e.g., `1.1.0-preview`).
|
||
- `include_narrative` (boolean, optional, default: `true`): Whether to include the narrative (`text` element) in the StructureDefinition. Set to `false` to strip the narrative.
|
||
- **Description**: Retrieves a specific StructureDefinition from the IG. Supports narrative stripping to reduce payload size.
|
||
- **Response**: A JSON object containing the StructureDefinition resource.
|
||
|
||
### Get Refresh Status
|
||
|
||
- **Endpoint**: `GET /status`
|
||
- **Description**: Returns the status of the last cache refresh, including the timestamp, package count, and any errors encountered.
|
||
- **Response**: A JSON object with refresh status details.
|
||
|
||
### Force Cache Refresh
|
||
|
||
- **Endpoint**: `POST /refresh-cache`
|
||
- **Description**: Forces an immediate refresh of the IG metadata cache by re-syncing with FHIR registries. This also resets the scheduled refresh timer to 8 hours from the time of the manual refresh.
|
||
- **Response**: A JSON object with the updated refresh status.

This response provides the `AUCoreAllergyIntolerance` StructureDefinition with the narrative included. To strip the narrative, set `include_narrative=false`, and the `text` element will be `null`.
|
||
|
||
## Testing IggyAPI
|
||
|
||
You can test IggyAPI using `curl`, Postman, or the Swagger UI.
|
||
|
||
### Using `curl`
|
||
|
||
1. **Search for IGs**:
|
||
```bash
|
||
curl -X GET "http://localhost:8000/igs/search?query=au%20core&search_type=semantic" -H "accept: application/json"
|
||
```
|
||
Look for `hl7.fhir.au.core` in the response.
|
||
|
||
2. **List Profiles**:
|
||
```bash
|
||
curl -X GET "http://localhost:8000/igs/hl7.fhir.au.core/profiles?version=1.1.0-preview" -H "accept: application/json"
|
||
```
|
||
Verify that profiles like `AUCoreAllergyIntolerance` are listed.
|
||
|
||
3. **Get a Profile with Narrative**:
|
||
```bash
|
||
curl -X GET "http://localhost:8000/igs/hl7.fhir.au.core/profiles/AUCoreAllergyIntolerance?version=1.1.0-preview&include_narrative=true" -H "accept: application/json"
|
||
```
|
||
Check that the `text` element contains narrative content.
|
||
|
||
4. **Get a Profile without Narrative**:
|
||
```bash
|
||
curl -X GET "http://localhost:8000/igs/hl7.fhir.au.core/profiles/AUCoreAllergyIntolerance?version=1.1.0-preview&include_narrative=false" -H "accept: application/json"
|
||
```
|
||
Confirm that the `text` element is `null`.
|
||
|
||
5. **Refresh Cache**:
|
||
```bash
|
||
curl -X POST "http://localhost:8000/refresh-cache" -H "accept: application/json"
|
||
```
|
||
Verify the response includes the updated `last_refresh` timestamp.
|
||
|
||
### Using Swagger UI
|
||
|
||
- Navigate to `http://localhost:8000/docs`.
|
||
- Use the interactive interface to execute the above requests and inspect responses.
|
||
|
||
### Using Postman
|
||
|
||
- Import the OpenAPI specification (`http://localhost:8000/openapi.json`) into Postman.
|
||
- Create requests for each endpoint and test with the parameters shown above.
|
||
|
||
## Implementation Details
|
||
|
||
- **Framework**: Built with FastAPI for high performance and automatic OpenAPI documentation.
|
||
- **Database**: Uses SQLite to cache IG metadata, with tables `cached_packages` and `registry_cache_info`.
|
||
- **Caching**:
|
||
- IG metadata is cached in memory and persisted to SQLite.
|
||
- The cache is refreshed every 8 hours or on demand via `/refresh-cache`.
|
||
- Profiles are cached in memory to reduce redundant downloads.
|
||
- **Search Functionality**: Uses SpaCy for semantic and string similarity matching, with rapidfuzz as a fallback for string searches.
|
||
- **Narrative Stripping**: The `include_narrative` parameter in the `get_profile` endpoint removes the `text` element from StructureDefinitions when set to `false`.
|
||
- **Dependencies**:
|
||
- `requests` and `feedparser` for fetching IG metadata from registries.
|
||
- `sqlalchemy` for database operations.
|
||
- `rapidfuzz` for fuzzy search functionality.
|
||
- `spacy` for semantic and string similarity searches.
|
||
- `tenacity` for retrying failed registry requests.
|
||
- **Error Handling**:
|
||
- Returns HTTP 400 for invalid input (e.g., malformed IG names).
|
||
- Returns HTTP 404 for missing IGs or profiles.
|
||
- Returns HTTP 500 for server errors, with detailed logs.
