cardinalityclj/s
OPTIONAL. Default :one. Can also be :many.
This option indicates that that this attribute either has a single value or a homogeneous set of values. It is an indication to reports/forms, and an indication to the storage layer about how the attribute will need to be stored.
WARNING: Not all database adapters support :many on non-reference types. See your database adapter for details.

enumerated-labelsclj/s
RECOMMENDED For data type :enum. A map from enumeration keyword to string (or a (fn [] string?) that defines
the label that should be used for the given enumeration (for example in dropdowns). See enumerated-values.
Labels default to a capitalized version of their keyword name.

field-style-configclj/s
A map of options that are used by the rendering plugin to augment the style of a rendered input.
Such configuration options are really up to the render plugin, but could include things like :input/props as
additional DOM k/v pairs to put on the input.

identitiesclj/s
OPTIONAL/REQUIRED. Database adapters usually require this option for persisted attributes.
A set of qualified keys of attributes that serve as an identity for an entity/doc/row. This is how a particular attribute declares where it "lives" in a persistent data model, and is used by database adapters to generate resolvers that can find this attribute.
Generally used with a database adapter setting to get the database to generate proper resolvers, and is almost
always used in tandem with ::attr/schema.
If this attribute will live as a column on multiple SQL tables, as a fact on many Datomic entities, etc., then you should list all of those identities under this key.

identity?clj/s
Boolean. Indicates that the attribute is used to identify rows/entities/documents in a data store.
Database adapters use this to figure out what the IDs are, and forms/reports use them to understand how to uniquely access/address data.

pc-inputclj/s
ALIAS to :com.wsscode.pathom.connect/input. A set of qualified keys that are required to be present in the
pc-resolve's input parameter for it to be able to work.
You can use this to "connect the dots" of a data graph that are not normally connected in the database (or even your data domain) directly.
For example, say you can figure out a user's GitHub repositories if you know their email address (and your data model already knows how to get to an email address from an account ID). You can specify something like this:
(defattr repositories :account.github/repositories :ref
{ao/pc-output [{:account.github/repositories [:github.repository/id]}]
ao/pc-input #{:account/email}
ao/pc-resolve (fn [{:keys [query-params] :as env} {:account/keys [email]}]
...code that looks up repos via email ...)})
Now, any time a query runs in a context where it can get from where it currently "is" in the data graph to
an account ID, it can use the account-id resolver (generated by the db adapter) to find the :account/email, which
then in turn can be passed to this resolver to get repository IDs. We're assuming here that there is another
resolver that can get from repository IDs to details.
A completely virtual resolution like this can also simply be generated with Pathom's defresolver, but defining them
in attributes means you can add additional info to them that is useful to other parts of RAD like form rendering.
See pc-resolve and pc-output. Also note: Any pathom keys you'd normally put in a pathom resolver options
map can be included in an attribute that is used to generate a Pathom resolver.
ALIAS to :com.wsscode.pathom.connect/input. A set of qualified keys that are required to be present in the
`pc-resolve`'s `input` parameter for it to be able to work.

...code that looks up repos via email ...)})

an account ID, it can use the account-id resolver (generated by the db adapter) to find the `:account/email`, which

map can be included in an attribute that is used to generate a Pathom resolver.
pc-outputclj/s
ALIAS to :com.wsscode.pathom.connect/output.
Defines the expected output of an attribute that generates its own data. Does nothing by itself, must be used with :com.wsscode.pathom.connect/resolve, and optionally :com.wsscode.pathom.connect/input.
If you are resolving a graph edge, then the attribute must be a :ref type and can include a target
that indicates what kind of entities/rows/docs this attribute resolves to.
(defattr all-accounts :account/all-accounts :ref
{ao/target :account/id
ao/pc-output [{:account/all-accounts [:account/id]}]
ao/pc-resolve (fn [{:keys [query-params] :as env} _]
#?(:clj
{:account/all-accounts (queries/get-all-accounts env query-params)}))})
If you are resolving a scalar, then just specify the correct type.
Remember that automatic resolver generation in database adapters will be able to resolve any other desired attributes of an entity/row/document based on the ID of it. Therefore a ref attribute like this will typically ONLY return the IDs of the items (though it may choose to return more if that case is judged to always be more efficient).
NOTE: Any pathom keys you'd normally put in a pathom resolver options map can be included in an attribute that is used to generate a Pathom resolver.

pc-resolveclj/s
ALIAS to :com.wsscode.pathom.connect/resolve. A (fn [env input]) that can resolve the pc-output of
an attribute.
env is your Pathom parser's current parsing environment, and will contain things like your active database
connection, a reference to the parser itself, query parameters, etc. This environment is completely open,
and is set up when you create the parser. Database adapters will document what they place here.
Must be used with :com.wsscode.pathom.connect/output, and optionally :com.wsscode.pathom.connect/input.

map can be included in an attribute that is used to generate a Pathom resolver.

read-only?clj/s
Boolean or (fn [form-instance attribute] boolean?). If true it indicates to the form and db layer that writes
of this value should not be allowed. Enforcement is an optional feature. See you database adapter and rendering
plugin for details.

required?clj/s
OPTIONAL. Boolean. Defaults to false.
Indicates that this attribute should always be present when it is placed on an entity/row/document. Database adapters may or may not be able to enforce this, so consider this option a hint to the db and UI layer. (i.e. You may need to write and install additional save middleware to enforce this constraint, if you need that level of validation).

schemaclj/s
OPTIONAL. A keyword.
Abstractly names a schema on which this attribute lives. Schemas are just names you make up that allow you to organize the physical location of attributes in databases. This option is typically used with some database-specific adapter option(s) to fully specify the details of storage.

styleclj/s
A keyword or (fn [context] keyword), where context will typically be a component instance that is attempting
to apply the style.
Indicates the general style for formatting this particular attribute in forms and reports. Forms and reports include additional more fine-grained options for customizing formatting, but this setting can be used as a hint to all plugins and libraries as to how you'd like the value to be styled.
Examples that might be defined include :USD, :password, :currency, etc. Support for this attribute
will depend on the specific RAD artifact, and may have no effect at all.

targetclj/s
REQUIRED for :ref attributes. A qualified keyword of an identity? true attribute that identifies the entities/rows/docs
to which this attribute refers.
If this attribute is a persisted edge (complex references can be resolved by resolvers and need not be reified in a database) then your database adapter will likely require other details so it can properly generate resolvers and save functionality.

On forms this function is OVERRIDDEN by the existence of a form validator.
DB adapters may use it. See your database plugin's documentation for more info.
