i'm tring to render a form base on triple, but the result is in flat array,
:用户表单 :render [
:render [
:name "用户名" ;
:type "text"
] ;
:render [
:name "姓名" ;
:type "text"
] ;
:render [
:name "角色" ;
:type "radio" ;
:option (:客服 :管理员)
]
] .
SELECT
?name
?type
?option
?value
WHERE {
:用户表单 :render ?用户表单 .
?用户表单 :render ?元素 .
?元素 :name ?name ;
:type ?type .
OPTIONAL {
?元素 :option ?option .
?option rdf:rest*/rdf:first ?value
}
}
[
{
"name": {
"type": "literal",
"value": "姓名"
},
"type": {
"type": "literal",
"value": "text"
}
},
{
"name": {
"type": "literal",
"value": "角色"
},
"type": {
"type": "literal",
"value": "radio"
},
"value": {
"type": "uri",
"value": "http://test/onto#客服"
},
"option": {
"type": "bnode",
"value": "bnode_02e58914_07f7_4b33_ad0d_896cf787d4d0_224"
}
},
{
"name": {
"type": "literal",
"value": "角色"
},
"type": {
"type": "literal",
"value": "radio"
},
"value": {
"type": "uri",

},
"option": {
"type": "bnode",

},
{
"name": {
"type": "literal",
"value": "用户名"
},
"type": {
"type": "literal",
"value": "text"
}
}
]
<form onSubmit={handleSubmit(onSubmit)}>
{elements.map(({ type, name }) => (
<div key={name.value}>
<label htmlFor={name.value}>{name.value}</label>
<input id={name.value} type={type.value} name={name.value} ref={register} />
</div>
))}
<div>
<input type='submit' value='提交' />
</div>
</form>
i've tied xml result, but this flat struct is hard to deal

what i expected is like a dom tree, form radio button will have options that nested, i wonder is there a best practice when dealing with sparql result ?

Have you looked at GraphQL?
graphql seems doesn't support unicode?
so i have to turn all schema into ascii?
trying to get rdf:List, but stucked
how to get :option (:Admin :Client)
{
Form {
render {
render {
name
type
option @optional
}
}
}
}
INSERT {
# 类
:User a owl:Class .
:Admin a owl:Class ;
rdfs:label "管理员" ;
rdfs:subClassOf :User .
:Client a owl:Class ;
rdfs:label "客服" ;
rdfs:subClassOf :User .
:Permission a owl:Class .
# 属性
:username a owl:DatatypeProperty ;
a owl:FunctionalProperty .
:name a owl:DatatypeProperty .
# 表单
:userForm a :Form ;
:render [
:render [
:name "用户名" ;
:type "text"
] ;
:render [
:name "姓名" ;
:type "text"
] ;
:render [
:name "角色" ;
:type "radio" ;
:option (:Admin :Client)
]
] .
# 创建一些默认用户
?crapthings
a :Client ;
:username "crapthings" ;
:name "张翃" .
?admin
a :Admin ;
:username "admin" ;
:name "管理员" .
}
WHERE {
BIND(:user:crapthings as ?crapthings) .
BIND(:user:admin as ?admin) .
}

The use of latin letters as identifiers appears to be a limitation in the GraphQL specification. We're leveraging the graphql-java library for parsing and as such don't have an easy way around this.

What result are you getting for option? The bnode representing the list?
scheme
INSERT {
# class
:User a owl:Class .
:Admin a owl:Class ;
rdfs:label "Administrator" ;
rdfs:subClassOf :User .
:Client a owl:Class ;
rdfs:label "Client" ;
rdfs:subClassOf :User .
:Permission a owl:Class .
# property
:username a owl:DatatypeProperty ;
a owl:FunctionalProperty .
:name a owl:DatatypeProperty .
# form
:userForm a :Form ;
:hasElement [
:hasInput [
:name "username" ;
:type "text"
] ;
:hasInput [
:name "name" ;
:type "text"
] ;
:hasInput [
:name "role" ;
:type "radio" ;
:hasOption (:Admin :Client)
]
] .
# create default users
?crapthings
a :Client ;
:username "crapthings" ;
:name "zhang hong" .
?admin
a :Admin ;
:username "admin" ;
:name "administrator" .
}
WHERE {
BIND(:user:crapthings as ?crapthings) .
BIND(:user:admin as ?admin) .
}
query
SELECT
*
WHERE {
:userForm :hasElement ?element .
?element :hasInput ?input .
?input :name ?name ;
:type ?type .
OPTIONAL {
?input :hasOption ?list .
?list rdf:rest*/rdf:first ?option .
}
}
graphql query
{
Form {
hasElement {
hasInput {
name
type
hasOption @optional
}
}
}
}
and i don't know what to do next, i think it should give me
rdfs:label at least
i'm still watching this video tutorial https://vimeo.com/318530180 , but got no clue

Yeah, I see. The list in RDF is represented as several triples. We'll have to add a new directive or something to handle it like this. I'll raise a new feature request.

and sometimes might nest in more detail form
:userForm a :Form ;
:hasElement [
:hasInput [
:name "username" ;
:type "text"
] ;
:hasInput [
:name "name" ;
:type "text"
] ;
:hasInput [
:name "role" ;
:type "radio" ;
:hasOption ([
:value "something1" ;
:label "Administrator"
] [
:value "something2" ;
:label "Client"
])
]
] .

That would be fine once we can support the lists. If it's a literal for the option, we should return the value in the array. If it's structured, you would need to list the fields, eg:
option {
value
label
}
