-This is a guide for converting plugins written for an earlier version of
-Veraison to the updated plugin framework.
-
-1. Remove `GetFormat()`. Attestation formats are no longer required --  the
-   combination of the plugin scheme (see (3) below) and media types is now used
-   to select plugins.
-2. Update `GetName()`. If this was previously implemented in terms of the
-   format. This can now be defined as a string constant.
-3. Add `GetAttestationScheme()` method. This should return a `string` naming
-   the attestation scheme you're implementing.
-
-   > **Warning**: it is important that both `IEndorsementHandler` and
-   > `IEvidinceHandler` implementations for a scheme return the same values for
-   > this -- it is the connection that allows the verification flow to
-   > correctly identify relevant endorsements provisioned via the provisioning
-   > flow.
-
-4. Replace `main()`. Instead of using HashiCorp APIs directly, Veraison now
-   provides a couple of methods to handle plugin creation.
-
-   Instead of some thing like
-
-   ```go
-   package main
-
-    import "github.com/hashicorp/go-plugin"
-
-    type Scheme struct {}
-
-    // ...
-    // Scheme implementation goes here
-    // ...
-
-    func main() {
-            var handshakeConfig = plugin.HandshakeConfig{
-                    ProtocolVersion:  1,
-                    MagicCookieKey:   "VERAISON_PLUGIN",
-                    MagicCookieValue: "VERAISON",
-            }
-
-            var pluginMap = map[string]plugin.Plugin{
-                    "scheme": &scheme.Plugin{
-                            Impl: &Scheme{},
-                    },
-            }
-
-            plugin.Serve(&plugin.ServeConfig{
-                    HandshakeConfig: handshakeConfig,
-                    Plugins:         pluginMap,
-            })
-    }
-   ```
-
-   You now need to do:
-
-   ```go
-    package main
-
-    import (
-            "github.com/veraison/services/handler"
-            "github.com/veraison/services/plugin"
-    )
-
-    type Scheme struct {}
-
-    // ...
-    // Scheme implementation goes here
-    // ...
-
-    func main() {
-            handler.RegisterEvidenceHandler(&Scheme{})
-            // note the change to the import of "plugin" above
-            plugin.Serve()
-    }
-   ```
-
-The above example is for the verification-side "scheme" plugins (note: these
-are now known as "evidence handlers" within Veraison code base, but the only
-API change is the removal of `GetFormat()` mentioned above.
-
-Identical changes would also need to be made to the provisioning-side "handler"
-plugins (now known as "endorsement handlers" within Veraison code base), with
-the only difference that `handler.RegisterEndorsementwHandler()` should be used
-instead inside `main()`.
-
-It is now also possible to build both plugins into a single binary, simply by
-registering both implementations:
-
-```go
-func main() {
-        handler.RegisterEvidenceHandler(&Scheme{})
-        handler.RegisterEndorsementHandler(&Decoder{})
-        plugin.Serve()
-}
-```

 ## Implementing Attestation Scheme Support
 
 > [!NOTE]
-> If you already have attestation scheme plugins implemented for an
-> earlier version of Veraison, please see the [migration guide](MIGRATING.md)
-> for how to convert them to the new framework.
-
-Supporting a new attestation scheme requires defining how to provision
-endorsements (if any) by implementing
-[`IEndorsementHandler`](../handler/iendorsementhandler.go), how to process
-evidence tokens by implementing
-[`IEvidenceHandler`](../handler/ievidencehandler.go), how to create and obtain
-scheme-specific keys used to store and retrieve endorsements and trust anchors
-by implementing [`IStoreHandler`](../handler/istorehandler.go), and how to
-handle CoSERV queries by implementing
-[`ICoservProxyHandler`](../handler/icoservproxyhandler.go).
-
-Finally, an executable should be created that [registers](../handler/plugin.go)
-and serves them.
+> `example` sub-directory contains a "template" for new scheme boiler plate.
+> You can start implementing a new scheme by copying it and filling in the 
+> TODO's.
+
+An implementation of an attestation scheme needs to provide two things:
+
+- A [`SchemeDescriptor`](../handler/schemedescriptor.go) providing basic
+  information about the scheme.
+- An implementation of
+  [`ISchemeImplementation`](../handler/ischemeimplementation.go) interface.
+
+Both of these need to then be registered
+
+- as a plugin by calling `handler.RegisterSchemeImpalementation`, and
+- for in-line implementations (i.e. those that are part of this code base), by
+  updating [builtin/schemes.go](../builtin/schemes.go)
+
 
 ```go
 package main
 
 import (
-	"github.com/veraison/services/decoder"
+	"github.com/veraison/services/handler"
 	"github.com/veraison/services/plugin"
 )
 
-type MyEvidenceHandler struct {}

+	VersionMajor: 1,
+	VersionMinor: 0,
+	CorimProfiles: []string{
+		"http://my-org/my-scheme",
+	},
+	EvidenceMediaTypes: []string{
+		"application/my-scheme-evidence",
+	},
+}
+

+	plugin.Serve()
+}
+```
 
-// ...
-// Implementation of IEndrosementHandler for MyEndrosementHandler
-// ...
+### Validating endorsements and trust anchors
 
-type MyStoreHandler struct {}
+Endorsements and trust anchors are provisioned as CoRIMs into the store using
+a standard provisioning flow. A scheme implementation does not need to worry
+about that except to make sure that the CoRIM provisioned for it contains the
+information it expects. 
 
-// ...
-// Implementation of IStoreHandler for MyStoreHandler
-// ...
+The recommended way to do that is to utilize the validation support provided by
+the CoRIM libraries [profile extensions
+mechanism](https://github.com/veraison/corim/blob/main/extensions/README.md).
+
+```go
+type TriplesValidator struct {}
 
-type MyCoservProxyHandler struct {}
+func (o *TriplesValidator) ValidTriples(triples *comid.Triples) error {
+    // make sure the triples contain the right data for the scheme, returning
+    // an error if they don't.
+
+	return nil
+}
+
+func init() {
+	extMap := extensions.NewMap().Add(comid.ExtTriples, &TriplesValidator{})
+
+    for _, profileString := range Descriptor.CorimProfiles {
+        profileID, err := eat.NewProfile(profileString)
+        if err != nil {
+            panic(err)
+        }
+
+        if err := corim.RegisterProfile(profileID, extMap); err != nil {
+            panic(err)
+        }
+    }
+}
+
+```
+
+To make this easier, we provide standard `TriplesValidator` implementation that
+only needs to be given callback validators for individual elements (such as
+environments). E.g.
+
+```go
+import (
+	"github.com/veraison/corim/comid"
+    "github.com/veraison/services/scheme/common"
+)
+
+func revValEnvValidator(e *comid.Environment) error {
+    // validate reference value environment
+    return nil
+}
+
+func taEnvValidator(e *comid.Environment) error {
+    // validate trust anchor environment
+    return nil
+}
+
+func measurementsValidator(meas []comid.Measurement) error {
+    // validate reference value measurements environment
+    return nil
+}
+
+func cryptoKeysValidator(keys []*comid.CryptoKeys) error {
+    // validate attestation verification keys
+    return  nil
+}
+
+var validator = &common.TriplesValidator{
+    TAEnviromentValidator: taEnvValidator,
+    RefValEnviromentValidator: refValEnvValidator,
+    // Alternatively to the above, EnvironmentValidator may specified, which
+    // will be invoked for both trust anchors and reference values.
+    CryptoKeysValidator: measurementsValidator,
+    MeasurementsValidator: cryptoKeysValidator,
+}
+
+func init() {
+	extMap := extensions.NewMap().Add(comid.ExtTriples, validator)
+
+    // ...
+}
+```
+Yo do not need to specify all the validator functions listed above -- just the
+ones for the elements you care about for your scheme.
+
+### `ISchemeHander`
+
+VTS actually expects [`ISchemeHander`](../handler/ischemehandler.go) to be
+implemented by plugins. [A wrapper](../handler/schemeimplementationwrapper.go)
+provides this based on the `SchemeDescriptor` and `ISchemeImplementation`. This
+results in a simpler, more declarative scheme definition.
+
+In general, it is recommended that new schemes are defined using
+`SchemeDescriptor` and `ISchemeImplementation` as described above. If, for
+whatever reason, this is not sufficient, it is possible to implement
+`ISchemeHandler` directly:
+
+```go
+package main
+
+import (
+	"github.com/veraison/services/handler"
+	"github.com/veraison/services/plugin"
+)
+
+type Handler struct {}
 
 // ...
-// Implementation of ICoservProxyHandler for MyCoservProxyHandler
+// Implementation of ISchemeHandler for Handler
 // ...
 
 func main() {
-	handler.RegisterEndorsementHandler(&MyEndorsementHandler{})
-	handler.RegisterEvidenceHandler(&MyEvidenceHandler{})
-	handler.RegisterStoreHandler(&MyStoreHandler{})
-	handler.RegisterCoservProxyHandler(&MyCoservProxyHandler{})
-
+	handler.RegisterSchemeHandler(&Handler{})
 	plugin.Serve()
 }
 ```
 
+(Note that `ISchemeHandler` embeds `ISchemeImplementation`, so you would still
+need to implement it.)
+
+## Guidance on structuring and using CoRIMs in attestation schemes
+
+> [!NOTE]
+> This section should viewed as supplementing section 5.1 of
+> [draft-ietf-rats-corim-09]. It describes how the CoRIMs are used by the
+> Veraison Trusted Services (VTS) and therefore how they may be used by
+> attestation schemes.
+
+VTS deals with endorsements (reference measurements) and trust anchors as basic
+units of provisioned data. This maps directly to `reference-triples` and
+`attest-key-triples` described in section 5.1.4 of [draft-ietf-rats-corim-09].
+
+Triples relevant to a particular attestation are identified based on their
+environments by matching them to the environments generated from the
+attestation evidence during verification flow.
+
+Keep in mind the following things when structuring CoRIMs for use with Veraison
+Services:
+
+- CoRIMs must contain _only_ CoMID tags; no other tags are supported. A CoRIM
+  may contain any number of CoMIDs.
+- Any information relevant to attestation verification must be contained
+  _solely_ within `reference-triples` and `attest-key-triples`
+  (`Triples.ReferenceValues` and `Triples.AttestVerifKeys` in the Go package)
+  [^1]. A CoMID may contain any number of these triples.
+- Meaning must NOT be assigned to the grouping of triples within a CoMID, or
+  grouping of CoMIDs within a CoRIM. This grouping information is not available
+  to the attestation schemes -- all relevant triples are retrieved as a single
+  list.
+- Meaning CAN be assigned to grouping of measurements within a single reference
+  value triple, or to the grouping of keys within a single attest. verif. key
+  triple.
+- Any information needed to match a triple to evidence must be contained
+  _solely_ in the triple's environment; and the environments must _only_
+  contain information needed to match a triple to evidence.
+
+Aside from the above constraints, the format of CoRIMs/CoMIDs is left up to the
+individual attestation schemes.
+
+[^1]: The CoRIM store used by VTS can also accommodate `identity-triples` and
+      `endorsed-triples`, however these will never be retrieved for verification.
+      The store does not currently support any other triple type and will return
+      an error when trying to add them.

+This directory contains the boilerplate structure for a new attestation scheme
+implementation. It is intended as a starting point.
+
+To create a new attestation scheme:
+
+1. Copy the contents of this directory into a new subdirectory under scheme,
+   e.g. `cp -r scheme/example scheme/my-scheme`.
+2. Update the `<TODO>` placeholders with relevant information, keeping the
+   following conventions in mind:
+   - `SchemeName` ought to be in all caps, with underscores separating words,
+     e.g. `"MY_SCHEME"`
+   - `GOPKG` should contain the scheme name in all lower case with dashes
+     instead of underscores, e.g.
+
+        GOPKG := github.com/veraison/services/scheme/my-scheme
+
+     (note: Go automatically translates dashes to underscores in package names
+     when parsing source, so your source  files should specify package as
+     `package my_scheme`).
+   - The name of the plugin executable should be the same name as `GOPKG` but
+     prefixed with `scheme-` (this is to distinguish from CoSERV backend
+     plugins) and use `.plugin` extension, e.g.
+
+        PLUGIN := ../../bin/scheme-my-plugin.plugin
+
+3. Update `scheme/Makefile` with a `SUBDIR` entry for your scheme.
+4. Update `builtin/schemes.go` with an entry for your scheme (see existing
+   entries there for an example).

-# SEV-SNP scheme
-
-This scheme supports the provisioning of reference values and appraisal of evidence. It is suitable for anyone performing verification of simple SEV-SNP evidence.
-
-## Installation
-
-It doesn't need any specific install instructions, it gets deployed along with other schemes.
-```
-make really-clean && make native-deploy
-```
-
-## Usage example
-
-Following is an example of how to interface with this scheme/plugin. The workflow involves using cocli to submit Reference Values and [ratsd](https://github.com/veraison/ratsd) to submit Evidence.
-
-Generating Reference Values and Evidence is beyond this project's scope. Please see [go-gen-ref](https://github.com/jraman567/go-gen-ref) for creating Reference Values for SEV-SNP; ratsd generates Evidence.
-
-### Provisioning Trust Anchor
-```
-cocli comid create --template scheme/sevsnp/test/ta-prov.json
-cocli corim create -m ta-prov.cbor -t corimMini.json -o ta.cbor
-cocli corim submit --corim-file=ta.cbor --api-server="https://localhost:9443/endorsement-provisioning/v1/submit" --media-type="application/corim-unsigned+cbor; profile=\"https://amd.com/ark\""
-```
-
-### Provisioning Reference Values
-```
-cocli corim submit --corim-file=scheme/sevsnp/test/refval-prov.cbor --api-server="https://localhost:9443/endorsement-provisioning/v1/submit" --media-type="application/corim-unsigned+cbor; profile=\"https://amd.com/ark\""
-```
-
-### Submitting Evidence
-```
-git clone https://github.com/veraison/ratsd.git
-cd ratsd; go build
-# From the following command, note down the nonce (in the body) and
-# session-id (location in the header), and save them as NONCE and
-# SESSION_ID environment variables respectively
-curl -sSk -X POST "https://<verifier-hostname-or-IP>:8443/challenge-response/v1/newSession?nonceSize=64" -H "accept: application/vnd.veraison.challenge-response-session+json" -i
-EVIDENCE_TOKEN=$(curl -sS -X POST http://<attester-hostname-or-IP>:8895/ratsd/chares -H "Content-Type: application/vnd.veraison.chares+json" -d "{\"nonce\":\"$NONCE\"}")
-ATTESTATION_RESULT=$(curl -sSk -X POST -H "https://localhost:8443/$SESSION_ID \
-  -H "accept: application/vnd.veraison.challenge-response-session+json" \
-  -H 'Content-Type: application/eat+cwt; eat_profile="tag:github.com,2025:veraison/ratsd/cmw"' \
-  -H "Host: localhost:8443" \
-  --data-raw "$EVIDENCE_TOKEN")
-echo $ATTESTATION_RESULT
-```
-
-## Result
-The result is in JWT format. We can print and verify the result using the [ARC tool](https://github.com/veraison/ear/tree/main/arc) as follows.
-```
-go install github.com/veraison/ear/arc@latest
-arc print result.jwt
-```
-The trustworthiness vector, as shown below, summarizes the result of verification.
-```
-    "SEVSNP": {
-      "ear.appraisal-policy-id": "policy:SEVSNP",
-      "ear.status": "affirming",

+SPECIFICATION
+
+A specification is A YAML document with the following top-level entries:
+
+  corim: path, relative to the spec, of the CoRIM JSON template (.json
+         extension can optionally be omitted). If the template contains the
+         "corim-id" entry, the segment (last six bytes) of this UUID will be
+         automatically, ovewritten with an auto-incrementing index for each
+         CoMID set (see below), starting at 1.
+
+ outdir: path, relative to the spec, of the output directory into which the
+         created CoRIM(s) will be written
+
+workdir: (optional) working directory (will be created) where intemediate
+         artifacts (compiled CoMIDs, populated CoRIM template, etc) will be
+         located. WARNING: if this directory exists, its prior contents will
+         be DELETED. If not specified, /tmp/create-corim-workdir will be used.
+
+   sign: (optional) boolean flag indicating whether a signed version of the
+         CoRIM will also be created. May be overridden on per-CoMID set level
+         (see below). If true, then the name of the unsigned CoRIM will be
+         prefixed with "unsigned-" and the signed CoRIM with "signed-". If this
+         is true then a key (see below) MUST also be specified. If not
+         specified, false is assumed.
+
+    key: (required when sign is true) path, relative to the spec, of the key
+         file that will be used to sign CoRIMs, if sign (see above) is true. If
+         sign is false, this will be ignored. May be overridden on per-CoMID
+         set level (see bellow). The key must be in a format understood by
+         cocli.
+
+   meta: (optonal) path, relative to the spec, of the JSON description that will
+         be used to generate the Meta entry when signing the CoRIM. If sign (see
+         above) is false, this will be ignored. If sign is true, and meta, is not
+         specified, an entry will instead be generated by the script.
+
+ comids: a mapping of names to CoMID sets (see next section). The name will be
+         used as the root of the name of the generated CoRIM. The CoRIM will
+         use the template specified by corim (see above) for top-level entries,
+         and will contain CoMIDs specified by the set.
+
+COMID SETS
+
+A CoMID set is either a map or a list describing the CoMIDs that will be used
+to create a CoRIM. If it is a map, it may contain the following entries:
+
