| 38 | + |
| 39 | +## 2. Grant of Rights |
| 40 | + |
| 41 | +Subject to the terms and limitations of this License, the Licensor grants You a |
| 42 | +worldwide, royalty-free, non-exclusive license to: |
| 43 | + |
| 44 | +(a) use, copy, and run the Licensed Work for any non-production purpose; |
| 45 | + |
| 46 | +(b) modify the Licensed Work and create derivative works of it; |
| 47 | + |
| 48 | +(c) redistribute the Licensed Work and Your derivative works, provided You comply |
| 49 | +with Section 5; and |
| 50 | + |
| 51 | +(d) make Production Use of the Licensed Work, except where such use is restricted by |
| 52 | +Section 3 or reserved to the Licensor by Section 4. |
| 53 | + |
| 54 | +## 3. Production Use Conditions |
| 55 | + |
| 56 | +The grant of Production Use in Section 2(d) does not extend to, and You may not |
| 57 | +without a separate commercial license from the Licensor: |
| 58 | + |
| 59 | +(a) provide a Competing Offering to third parties; or |
| 60 | + |
| 61 | +(b) offer the Licensed Work, or any derivative work of it, to third parties on a |
| 62 | +hosted, embedded, or as-a-service basis where doing so competes with the Licensor's |
| 63 | +commercial interests in the Licensed Work. |
| 64 | + |
| 65 | +"Embedded" includes incorporating the source or object code of the Licensed Work |
| 66 | +into a Competing Offering, and packaging a Competing Offering such that the Licensed |
| 67 | +Work must be accessed or downloaded for that offering to function. |
| 68 | + |
| 69 | +Hosting or using the Licensed Work for Your own internal purposes is not a Competing |
| 70 | +Offering and is permitted, including across Your affiliates under common control. |
| 71 | + |
| 72 | +## 4. Reserved Rights |
| 73 | + |
| 74 | +Notwithstanding any other provision of this License, the Licensor reserves to itself |
| 75 | +the exclusive right to build, operate, offer, or authorize a Commercial Marketplace |
| 76 | +that incorporates, integrates, is built upon, or otherwise uses the Licensed Work. |
| 77 | + |
| 78 | +This License grants You no right to construct, operate, or enable a Commercial |
| 79 | +Marketplace using the Licensed Work, whether on a commercial or non-commercial basis, |
| 80 | +and any such use requires a separate written agreement with the Licensor. |
| 81 | + |
| 82 | +## 5. Redistribution |
| 83 | + |
| 84 | +If You redistribute the Licensed Work or any derivative work of it, in original or |
| 85 | +modified form, You must: |
| 86 | + |
| 87 | +(a) include a complete, unmodified copy of this License with each copy; and |
| 88 | + |
| 89 | +(b) cause any recipient to receive the Licensed Work subject to the terms of this |
| 90 | +License. |
| 91 | + |
| 92 | +The conditions in Sections 3 and 4 apply to every recipient of the Licensed Work, |
| 93 | +whether received directly from the Licensor or through a third party. |
| 94 | + |
| 95 | +## 6. Conversion to Open Source |
| 96 | + |
| 97 | +For each version of the Licensed Work, on the tenth anniversary of the date the |
| 98 | +Licensor first made that version publicly available (the "Change Date" for that |
| 99 | +version), the Licensor additionally grants You the right to use that version under |
| 100 | +the terms of the Apache License, Version 2.0, and on and after that version's Change |
| 101 | +Date the restrictions in Sections 3 and 4 no longer apply to that version. |
| 102 | + |
| 103 | +This License applies separately to each version of the Licensed Work, and the Change |
| 104 | +Date may differ between versions. |
| 105 | + |
| 106 | +## 7. Commercial Licensing |
| 107 | + |
| 108 | +If Your intended use is not permitted under this License, You may obtain a separate |
| 109 | +commercial license from the Licensor by contacting hello@query.farm. Absent such a |
| 110 | +license, You must refrain from the restricted use. |
| 111 | + |
| 112 | +## 8. Trademarks |
| 113 | + |
| 114 | +This License does not grant You any right to use the names, trademarks, service |
| 115 | +marks, or logos of the Licensor, including "Vector Gateway Interface," "VGI," and |
| 116 | +"Hyperfederation," except as required for reasonable and customary use in describing |
| 117 | +the origin of the Licensed Work. |
| 118 | + |
| 119 | +## 9. Termination |
| 120 | + |
| 121 | +Any use of the Licensed Work in violation of this License automatically terminates |
| 122 | +Your rights under this License for the current and all other versions of the Licensed |
| 123 | +Work. Your rights may be reinstated only by a writing signed by the Licensor. |
| 124 | + |

| 131 | + |
| 132 | +TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL THE LICENSOR BE |
