## Under current schema

### Fetching script info

`hydrilla.example.com/script?n=helloscript` returns:

``` javascript

{

    "name": "helloscript",

    "location": "somedirectory/hello.js",

    "sha256":   "e4dbe4dba40e8bd159fb987b0f0cf2c243d7e6b9b9dc792e58dedf1fae38b0a1"

}

```

or 404 Not Found in case "helloscript" script does not exist. `hydrilla.example.com/content/somedirectory/hello.js` holds the actual script source.

### Fetching bag info

`hydrilla.example.com/bag?n=hellobag` returns:

``` javascript

{

    "name": "hellobag",

    "components":   [["s", "helloscript"], ["s", "someotherscript"], ["b", "somebag"]]

}

```

or 404 Not Found in case "hellobag" bag does not exist.

### Fetching pattern info

`hydrilla.example.com/pattern?n=https://example.org/a/*` returns:

``` javascript

{

    "pattern":  "https://example.org/a/*",

    "payload":  ["b", "hellobag"]

}

```

or 404 Not Found in case requested pattern does not exist.

### Querying patterns that match given URL

Finally, `hydrilla.example.com/query?n=https://example.org/a/b` returns:

``` javascript

[{

        "pattern":  "https://example.org/a/*",

        "payload":  ["b", "hellobag"]

    }, {

        "pattern":  "https://example.org/a/b",

        "payload":  ["b", "fix_by_mrcooldev"]

    }, {

        "pattern":  "https://example.org/a/b",

        "payload":  ["b", "mod_by_missgreatskill"]

    }]

```

or in case no patterns match the requested URL, it returns just:

``` javascript

[]

```

or in case the URL is of wrong format it returns some HTTP error.

## Under the upcoming schema

Also, once we get to do the redesign discussed in [this forum thread](/boards/1/topics/56), current interface will be replaced with the one described below (although some changes are still possible to happen!). In the examples below we assume base URL of the API server is `https://hydrilla.example.com/`.

### Fetching resource info

"resource" is now the equivalent of what we used to call "bag".

Let's assume we want to retrieve the definition of resource `helloapple`. We can issue a GET to `https://hydrilla.example.com/resource/helloapple.json`. It returns:

``` javascript

{

    "$schema": "https://hydrilla.koszko.org/schemas/api_resource_description-1.schema.json",

    "source_name": "hello",

    "source_copyright": [

        {

            "file": "report.spdx",

            "sha256": "249599a36ad9f6f33b8bf16ca6ace2413d95d8cdb481173968fa4e97fd0a5635"

        },

        {

            "file": "LICENSES/CC0-1.0.txt",

            "sha256": "a2010f343487d3f7618affe54f789f5487602331c0a8d03f49e9a7c547cf0499"

        }

    ],

    "type": "resource",

    "identifier": "helloapple",

    "long_name": "Hello Apple",

    "uuid": "a6754dcb-58d8-4b7a-a245-24fd7ad4cd68",

    "version": [

        2021,

        11,

        10

    ],

    "revision": 1,

    "description": "greets an apple",

    "dependencies": [

        {

            "identifier": "hello-message"

        }

    ],

    "scripts": [

        {

            "file": "hello.js",

            "sha256": "18dd7d7ac9f74a5ba871791ac6aa4d55530a336ae1b373538b6dd5320b330414"

        },

        {

            "file": "bye.js",

            "sha256": "cee8d88cf5e5346522fd9ee5e1f994b335fb68d2f460b27b2a2a05f0bcd2b55b"

        }

    ]

}

```

or 404 Not Found in case resource `helloapple` does not exists. If multiple versions are available, newest version's JSON description gets returned. A different one can be retrieved by including version in the GET request. Requested path should then take the form `/resource/<resource_name>/<version>` (e.g. `GET https://hydrilla.example.com/resource/helloapple/2021.11.9`).

File can be retrieved by issuing a GET request to `https://hydrilla.example.com/file/sha256/<file's_sha256_sum>`. For example, requests to `https://hydrilla.example.com/file/sha256/a2010f343487d3f7618affe54f789f5487602331c0a8d03f49e9a7c547cf0499` and `hydrilla.example.com/file/sha256/18dd7d7ac9f74a5ba871791ac6aa4d55530a336ae1b373538b6dd5320b330414` yield contents of `LICENSES/CC0-1.0.txt` and `hello.js`, respectively.)

A [JSON schema](https://json-schema.org) describing resource definition format is available [here](https://hydrilla.koszko.org/schemas/api_resource_description-1.schema.json).

### Fetching mapping info

"mapping" is now a set of what we used to call "pattern".

Let's assume we want to retrieve the definition of mapping `helloapple` (mapping is allowed to have the same identifier as a resource). We can issue a GET to `https://hydrilla.example.com/mapping/helloapple.json`. It returns:

``` javascript

{

    "$schema": "https://hydrilla.koszko.org/schemas/api_mapping_description-1.schema.json",

    "source_name": "hello",

    "source_copyright": [

        {

            "file": "report.spdx",

            "sha256": "249599a36ad9f6f33b8bf16ca6ace2413d95d8cdb481173968fa4e97fd0a5635"

        },

        {

            "file": "LICENSES/CC0-1.0.txt",

            "sha256": "a2010f343487d3f7618affe54f789f5487602331c0a8d03f49e9a7c547cf0499"

        }

    ],

    "type": "mapping",

    "identifier": "helloapple",

    "long_name": "Hello Apple",

    "uuid": "54d23bba-472e-42f5-9194-eaa24c0e3ee7",

    "version": [

        2021,

        11,

        10

    ],

    "description": "causes apple to get greeted on Hydrillabugs issue tracker",

    "payloads": {

        "https://hydrillabugs.koszko.org/***": {

            "identifier": "helloapple"

        },

        "https://hachettebugs.koszko.org/***": {

            "identifier": "helloapple"

        }

    }

}

```

or 404 Not Found in case `helloapple` mapping does not exist. If multiple versions are available, newest version's JSON description gets returned. A different one can be retrieved by including version in the GET request. Requested path should then take the form `/mapping/<mapping_name>/<version>` (e.g. `GET https://hydrilla.example.com/mapping/helloapple/2021.11.8`).

File can be retrieved by issuing a GET request to `https://hydrilla.example.com/file/sha256/<file's_sha256_sum>`. For example, request to `https://hydrilla.example.com/file/sha256/a2010f343487d3f7618affe54f789f5487602331c0a8d03f49e9a7c547cf0499` yields contents of `LICENSES/CC0-1.0.txt`.

A [JSON schema](https://json-schema.org) describing mapping definition format is available [here](https://hydrilla.koszko.org/schemas/api_mapping_description-1.schema.json).

### Querying mappings that match given URL

Assume we want to query mappings with patterns matching `https://example.org/a/b`. We can issue a GET to `https://hydrilla.example.com/query?url=https://example.org/a/b`. It returns:

``` javascript

{

    "$schema": "https://hydrilla.koszko.org/schemas/api_query_result-1.schema.json",

    "mappings": [

        {

            "identifier": "example-org-minimal",

            "long_name": "Example.org Minimal",

            "version": [

                2022,

                5,

                10

            ]

        },

        {

            "identifier": "example-org-experimental",

            "long_name": "example.org fix bundle",

            "version": [

                0,

                4

            ]

        }

    ]

}

```

The value of "mappings" can be an empty array (`[]`) in case no mappings match given URL. In case many versions of some mapping match the URL, only the most current of those versions that do is listed. In case the URL is of wrong format, 400 Bad Request is returned.

A [JSON schema](https://json-schema.org) describing query result format is available [here](https://hydrilla.koszko.org/schemas/api_query_result-1.schema.json).

### Fetching source info

By "source" we mean description of a source package used to build Hydrilla site content.

Assume we want to get description of source package `hello`. We can issue a GET to `https://hydrilla.example.com/source/hello.json`. It returns:

``` javascript

{

    "$schema": "https://hydrilla.koszko.org/schemas/api_source_description-1.schema.json",

    "source_name": "hello",

    "source_copyright": [

        {

            "file": "report.spdx",

            "sha256": "249599a36ad9f6f33b8bf16ca6ace2413d95d8cdb481173968fa4e97fd0a5635"

        },

        {

            "file": "LICENSES/CC0-1.0.txt",

            "sha256": "a2010f343487d3f7618affe54f789f5487602331c0a8d03f49e9a7c547cf0499"

        }

    ],

    "source_archives": {

        "zip": {

            "sha256": "f61bfc5594a2603452a8c8e5f7a3f36f255bc39d5ffea02c9fdefc0de6461c74"

        }

    },

    "upstream_url": "https://git.koszko.org/hydrilla-source-package-example",

    "definitions": [

        {

            "type": "resource",

            "identifier": "helloapple",

            "long_name": "Hello Apple",

            "version": [

                2021,

                11,

                10

            ]

        },

        {

            "type": "resource",

            "identifier": "hello-message",

            "long_name": "Hello Message",

            "version": [

                2021,

                11,

                10

            ]

        },

        {

            "type": "mapping",

            "identifier": "helloapple",

            "long_name": "Hello Apple",

            "version": [

                2021,

                11,

                10

            ]

        }

    ]

}

```

Or 404 Not Found in case no such source package exists. Here `zip` was listed among available source archive extensions. It means we can download the zip archive of this source package by issuing GET to `https://hydrilla.example.com/source/hello.zip`.

With schema version beginning with major number 1, zip archive is always guaranteed to be available.

A [JSON schema](https://json-schema.org) describing source package description format is available [here](https://hydrilla.koszko.org/schemas/api_source_description-1.schema.json).
