- AGPL dependency for → network servicealso  items of
- Apache 2.0 ↔ GPL 2.0  (  )

## license optional ofdecision tree

```
project target
├── maximum   → MIT or Apache 2.0
│   ├──   necessary → Apache 2.0
│   └── maximum simple → MIT
├── modification items  (day ) → MPL 2.0
├── library,  allowed → LGPL 3.0
├──  before items  → GPL 3.0
├── SaaS included items  → AGPL 3.0
└──  license (OSS + upperfor) → GPL + Commercial
```

## dependency license  resolution

###  patternand resolution

|  |  | resolution |
|------|------|------|
| MIT project + GPL dependency | GPL before |  package  or GPL transition |
| Apache + GPL 2.0 |    | GPL 3.0 before for |
| upperfor product + AGPL dependency |  items of |  package or license  |
|  GPL before  | before compatibility | "GPL 2.0 or later" for |

### license audit also

```bash
# Node.js
npx license-checker --json --production

# Python
pip-licenses --format=json --with-urls

# Go
go-licenses check ./...

# for
scancode-toolkit --json-pp output.json src/
```

## SPDX license 

```
# day license
SPDX-License-Identifier: MIT

# OR (optional possible)
SPDX-License-Identifier: MIT OR Apache-2.0

# AND ( license  compliant)
SPDX-License-Identifier: MIT AND BSD-3-Clause

# WITH (outside included)
SPDX-License-Identifier: GPL-2.0-only WITH Classpath-exception-2.0
```

##  license strategy

```
Community Edition: AGPL 3.0
├──  for possible
├── modification + service provided   items of
└── items/ open source projectin suitable

Enterprise Edition: upperfor license
├── AGPL of 
├── addition /supported included
└──  customer upper

success : MongoDB(SSPL), Redis(RSALv2), MySQL(GPL+Commercial)
```
