+# Annex I: Cross referencing in SPDX 3 (Informative)
+
+This document will walk though how to refer to SPDX Elements across documents
+(e.g. cross reference).
+
+If you do would like to construct the complete example documents from this
+Markdown file, use the following command:
+
+```shell
+cat cross-reference.md | awk 'BEGIN{flag=0} /^```json/, $0=="```" { if (/^---$/){flag++} else if ($0 !~ /^```.*/ ) print $0 > "doc-" flag ".spdx.json"}'
+```
+
+## Linking via spdxId
+
+It is frequently desired (and necessary) to reference an SPDX 3
+[Element][Class_Element] that lives in one document from another. Since SPDX
+documents are valid [JSON-LD][JSON_LD] documents, linking elements together can
+be as simple as referencing the spdxId of one element from another (in the same
+way that doing so within a document links Elements together. For example,
+assume we have this document that contains a [Person][Class_Person] we want to
+reference in another document:
+
+```json
+{
+    "@context": "https://spdx.org/rdf/3.0.0/spdx-context.jsonld",
+    "@graph": [
+        {
+            "type": "Person",
+            "spdxId": "http://spdx.example.com/Person/JoshuaWatt",
+            "creationInfo": "_:creationinfo",
+            "name": "Joshua Watt",
+            "externalIdentifier": [
+                {
+                    "type": "ExternalIdentifier",
+                    "externalIdentifierType": "email",
+                    "identifier": "JPEWhacker@gmail.com"
+                }
+            ]
+        },
+        {
+            "type": "CreationInfo",
+            "@id": "_:creationinfo",
+            "specVersion": "3.0.0",
+            "createdBy": [
+                "http://spdx.example.com/Person/JoshuaWatt"
+            ],
+            "created": "2024-03-06T00:00:00Z"
+        },
+        {
+            "type": "SpdxDocument",
+            "spdxId": "http://spdx.example.com/Document1",
+            "creationInfo": "_:creationinfo",
+            "profileConformance": [
+                "core"
+            ],
+            "rootElement": [
+                "http://spdx.example.com/Person/JoshuaWatt"
+            ]
+        }
+    ]
+}
+```
+
+Now, in our new document we can reference the "Joshua Watt" person by simply
+referring to it by its spdxId. For example, to indicate that this new document
+was also written by the same person, we can reference it in the creation info
+(note the [createdBy][Property_createdBy] property):
+
+```json
+---
+{
+    "@context": "https://spdx.org/rdf/3.0.0/spdx-context.jsonld",
+    "@graph": [
+        {
+            "type": "CreationInfo",
+            "@id": "_:creationinfo1",
+            "specVersion": "3.0.0",
+            "createdBy": [
+                "http://spdx.example.com/Person/JoshuaWatt"
+            ],
+            "created": "2024-05-08T00:00:00Z"
+        },
+```
+
+## Imports
+
+This is sufficient to link documents in JSON-LD, but it is missing some useful
+information that SPDX requires you to specify. Namely, since spdxIds are _not_
+necessarily resolvable URLs, this gives no indication as to where the
+[Person][Class_Person] can be found. In order to provide this information, SPDX
+requires that all externally referenced spdxIds be enumerated in the
+[imports][Property_imports] property of the local
+[SpdxDocument][Class_SpdxDocument]. Lets start by writing the preamble for the
+SpdxDocument:
+
+```json
+        {
+            "type": "SpdxDocument",
+            "spdxId": "http://spdx.example.com/Document2",
+            "creationInfo": "_:creationinfo1",
+            "profileConformance": [
+                "core",
+                "software"
+            ],
+            "imports": [
+```
+
+The [imports][Property_imports] property is a list of
+[ExternalMap][Class_ExternalMap] objects, one for each external spdxId being
+referenced. The class has one required property called
+[externalSpdxId][Property_externalSpdxId] which is the external spdxId being
+described:
+
+```json
+                {
+                    "type": "ExternalMap",
+                    "externalSpdxId": "http://spdx.example.com/Person/JoshuaWatt",
+```
+
+In addition to this, there are a few optional fields. The first is the
+[locationHint][Property_locationHint] property which is a URI that indicates
+where the document that contains the external spdxId may be located. Since this
+is an actual resolvable URI, consumers of the document can use locate the
+unresolved spdxId. While optional, this field is recommended:
+
+```json
+                    "locationHint": "http://downloads.example.com/Document1.spdx.json",
+```
+
+In addition to the location, the [verifiedUsing][Property_verifiedUsing]
+property indicates how a user can verify the integrity of the external document
+to ensure it has not been tampered with. It can be 0 or more
+[IntegrityMethod][Class_IntegrityMethod] objects. While also optional, it is
+recommended to include at least one:
+
+```json
+                    "verifiedUsing": [{
+                        "type": "Hash",
+                        "algorithm": "sha256",
+                        "hashValue": "3ba8c249c1ba1b6fe20582de88a5123b317632a5a94ba27199d01724df4eb149"
+                    }],
+```
+
+Finally, the [definingArtifact][Property_definingArtifact] allows a much richer
+expression of information about the document that contains the external spdxId
+by linking to a complete [Artifact][Class_Artifact] element. This field is also
+optional, but if you need the impressive expressive power of the `Artifact`
+class, it is also recommended:
+
+```json
+                    "definingArtifact": "http://spdx.example.com/Document1-Artifact"
+```
+
+It should be noted that it is reasonable for the `definingArtifact` itself to
+be an external spdxId, as long as it also has the relevant entry in `imports`.
+
+We also need to add an import for the [SpdxDocument][Class_SpdxDocument] that
+contains the author, as we will be referencing it later, so lets do that now:
+
+```json
+                },
+                {
+                    "type": "ExternalMap",
+                    "externalSpdxId": "http://spdx.example.com/Document1",
+                    "locationHint": "http://downloads.example.com/Document1.spdx.json",
+                    "verifiedUsing": [{
+                        "type": "Hash",
+                        "algorithm": "sha256",
+                        "hashValue": "3ba8c249c1ba1b6fe20582de88a5123b317632a5a94ba27199d01724df4eb149"
+                    }],
+                    "definingArtifact": "http://spdx.example.com/Document1-Artifact"
+                }
+```
+
+And that is it! By providing this information you are explaining to consumer of
+the document how they can resolve the external spdxIds.
+
+Lets close out our SpdxDocument
+
+```json
+            ]
+        },
+```
+
+Since we are using an [Artifact][Class_Artifact] that describes the SpdxDocument
+containing the external spdxId, we need to write that now:
+
+```json
+        {
+            "type": "software_File",
+            "spdxId": "http://spdx.example.com/Document1-Artifact",
+            "creationInfo": "_:creationinfo1",
+            "software_fileKind": "file",
+            "software_primaryPurpose": "file",
+            "software_contentType": "application/spdx+json",
+            "verifiedUsing": [{
+                "type": "Hash",
+                "algorithm": "sha256",
+                "hashValue": "3ba8c249c1ba1b6fe20582de88a5123b317632a5a94ba27199d01724df4eb149"
+            }],
+            "originatedBy": [
+                "http://spdx.example.com/Person/JoshuaWatt"
+            ],
+            "suppliedBy": "http://spdx.example.com/Person/JoshuaWatt",
+            "releaseTime": "2024-03-06T00:00:00Z",
+            "builtTime": "2024-03-06T00:00:00Z"
+        },
+```
+
+Finally, since we are using an [Artifact][Class_Artifact], we need to add a
+[Relationship][Class_Relationship] with type `serailizedInArtifact` to link the
+artifact and the serialized [SpdxDocument][Class_SpdxDocument]. Note that this
+is where the `spdxId` of the `SpdxDocument` is referenced which is why we
+needed to import it earlier:
+
+```json
+        {
+            "spdxId": "http://spdx.example.com/Document1-serializedInArtifact-Artifact",
+            "type": "Relationship",
+            "creationInfo": "_:creationinfo1",
+            "relationshipType": "serializedInArtifact",
+            "from": "http://spdx.example.com/Document1",
+            "to": [
+                "http://spdx.example.com/Document1-Artifact"
+            ]
+        }
+    ]
+}
+```
+
