| 1 | Binary Resource Format | hl7.fhir.uv.tools#current | R5 | This extension specifies the format (= mime type) of a binary resource, when the binary resource is provided to the IG publisher as raw content (rather than as a FHIR binary resource with base64 content). | |
| 2 | Binary Resource Logical | hl7.fhir.uv.tools#current | R5 | This extension specifies a logical model to use to validate the binary contents. | |

| 5 | IG Internal Dependency | hl7.fhir.uv.tools#current | R5 | A package (id#ver) that this IG has an internal dependency on. A internal dependency is a package that is required to validate the resources in the IG itself but that is not required by the implementers of the IG | |
| 6 | IG Link Dependency | hl7.fhir.uv.tools#current | R5 | A package (id#ver) that has pages that this IG references, without depending on. The sole purpose of defining these IGs is to inform the publisher link checker that links to this IG are valid | |

| 8 | IG Parameter | hl7.fhir.uv.tools#current | R5 | An implementation guide parameter defined by the HL7 IG Publisher. This is used in R4 IGs where the binding to paramater name prevented the use of additional parameters | |
| 9 | IG Publisher Bundle | hl7.fhir.uv.tools#current | R5 | Instructs the IG publisher to load a bundle when loading the source, but to treat all the resources found in the bundle as independent resources in the IG (e.g. not a bundle). Use this for bundles of examples | |
| 10 | ImplementationGuide Source File | hl7.fhir.uv.extensions.r4#1.0.0 | R4 | Identifies files used as part of the the publication process other than resources referenced in definition.resource. | |
| 11 | ModelInfo Settings | hl7.fhir.uv.crmi#current | R4 | Specifies the settings to be used for constructing modelinfo from profile definitions. | |

| 15 | Resource Approval Date | hl7.fhir.uv.extensions.r4#1.0.0 | R4 | The date on which the asset content was approved by the publisher. Approval happens once when the content is officially approved for usage. | |
| 16 | Resource Effective Period | hl7.fhir.uv.extensions.r4#1.0.0 | R4 | The period during which the resource content was or is planned to be effective. | |
| 17 | Resource Last Review Date | hl7.fhir.uv.extensions.r4#1.0.0 | R4 | The date on which the asset content was last reviewed. Review happens periodically after that, but doesn't change the original approval date. | |
| 18 | Resource Sort Extension | hl7.fhir.uv.tools#current | R5 | Allows assertion of a sort order for a resource in the list of artifacts within the IG |
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 13 | 13 | 14 | 15 | 16 | 17 | 18 | |
