R&S Entity Attribute for SPs
All R&S SPs satisfy the requirements of the REFEDS R&S Entity Category and therefore every R&S SP carries the refeds.org R&S entity attribute value in its metadata. For backwards compatibility, an R&S SP also carries the legacy incommon.org R&S entity attribute value and therefore every R&S SP has the following multivalued entity attribute in metadata (whitespace and comments added for readability):
| Code Block | ||
|---|---|---|
| ||
<mdattr:EntityAttributes xmlns:mdattr="urn:oasis:names:tc:SAML:metadata:attribute">
<!-- multivalued entity attribute for R&S SPs -->
<saml:Attribute
xmlns:saml="urn:oasis:names:tc:SAML:2.0:assertion"
NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:uri"
Name="http://macedir.org/entity-category">
<!-- the incommon.org R&S entity attribute value -->
<saml:AttributeValue>

The legacy incommon.org R&S entity attribute value is included in SP metadata for backwards compatibility only.
| Warning | ||
|---|---|---|
| ||
Note well that the legacy incommon.org R&S entity attribute value shown above is filtered from SP metadata exported to eduGAIN. Only the refeds.org R&S entity attribute value is exported to eduGAIN. |
| Warning | ||
|---|---|---|
| ||
| Use of the legacy incommon.org R&S tag to configure attribute release policy at the IdP is deprecated. Eventually this tag will be removed from all SP metadata although a timeline for doing so has not yet been determined. |
...
Note: The InCommon Registrar is authoritative for the above entity attribute. There is nothing an SP owner needs to do to manage this entity attribute.

These mutually exclusive support categories are indicated in IdP metadata by one of the following two entity attributes (resp.).
An IdP that releases attributes to all R&S SPs, including R&S SPs in other federations, has the following entity attribute in metadata (whitespace and comments added for readability):
| Code Block | ||
|---|---|---|
| ||
<mdattr:EntityAttributes xmlns:mdattr="urn:oasis:names:tc:SAML:metadata:attribute">
<!-- entity attribute for IdPs that support R&S SPs globally -->
<saml:Attribute
xmlns:saml="urn:oasis:names:tc:SAML:2.0:assertion"
NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:uri"
Name="http://macedir.org/entity-category-support">
<!-- the refeds.org R&S entity attribute value -->
<saml:AttributeValue>
http://refeds.org/category/research-and-scholarship
</saml:AttributeValue>
</saml:Attribute>
</mdattr:EntityAttributes> |
An IdP that releases attributes to R&S SPs registered by InCommon only has the following entity attribute in metadata (whitespace and comments added for readability):
| Code Block | ||
|---|---|---|
| ||
<mdattr:EntityAttributes xmlns:mdattr="urn:oasis:names:tc:SAML:metadata:attribute">
<!-- entity attribute for IdPs that support R&S SPs registered by InCommon -->
<saml:Attribute
xmlns:saml="urn:oasis:names:tc:SAML:2.0:assertion"
NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:uri"

</saml:AttributeValue>
</saml:Attribute>
</mdattr:EntityAttributes> |
The incommon.org R&S entity attribute value in IdP metadata has no meaning outside the InCommon Federation.
| Warning | ||
|---|---|---|
| ||
Although the incommon.org R&S entity attribute value shown above is exported to eduGAIN, it has no recognized semantics outside the InCommon Federation. Only IdPs that release attributes to all R&S SPs globally are recognized as R&S IdPs by the international R&E community. |
The fact that the R&S entity attribute in IdP metadata is single-valued has consequences for certain SPs.
...
| Tip |
|---|
An R&S IdP that supports global R&S is shown in green on the Entity Categories info page. |
Note: The IdP owner is authoritative for the above entity attributes. An IdP indicates its willingness and ability to support R&S by following the steps on the IdP support page for R&S.
