Ah Ok, if the issue is to convert a string (teamId) to a URI then maybe try
{= IRI(CONCAT("http://namespace-whatever#";, str(?teamId))) }

Thanks, Holger.
I actually tried to simplify the real code but in doing so I realize I
made it misleading. The parameter for the outer ui:call is not teamId
in the actual use case. It's something that could return multiple
teamIds, say something like jerseyColor. Multiple teams could result
but I'd be looking for the players and their former teams for multiple
teams by the current teamId. Does that make sense?
I hadn't noticed the inconsistently escaped double-quotes. They are
like that in the real code too. Seems like that would cause issues
but it's (mostly) working as expected except for the parameter to the
inner ui:call. Worth noting that with my small sample set so far I'm
only getting one "team" back so far so perhaps the quote issue would
reveal itself once I expand my testing.
Should I be trying to ui:concat with formerTeam: and ?teamId ? I
played around with that but could not get the syntax right.
Thank you, Adrian.

Hello,
I'm trying to create the following JSON structure for return from
a web service call:
"players" : [
{
"playerId" : "123",
"playerName" : "JD Martinez",
"playerCurrentTeam" : "Boston Redsox",
"teamId" : "1000",
"playerFormerTeams" : [
"Diamondbacks",
"Tigers",
"Astros"
]
},
{
"playerId" : "456",
"playerName" : "Chris Sale",
"playerCurrentTeam" : "Boston Redsox",
"teamId" : "1000",
"playerFormerTeams" : [
"Whitesox",
"Dodgers"
]
}
]
I'm being given access to two SPIN templates to call:
1. returns all current players for a team whose value is passed
in as a parameter.
2. returns all former teams for player whose value is a result of
the id in the first template (1000 in the case above).
@prefix former_team: <http://metadata.mlb.org/teams/team_data#>
<http://metadata.mlb.org/teams/team_data#> .
<swon:Value arg:name=\"players\">
<swon:Array>
<swon:Object>
<ui:call arg:team_id=\"{= ?team_id }\" ui:template=\"{=
int-spin:PlayersByTeamIdTemplate }\" ui:varName=\"rs\">
<ui:forEach
ui:bindVars="?playerId,?playerName,?playerCurrentTeam,?teamId"
ui:resultSet="{= ?rs }">
<swon:Value arg:name="playerId" arg:value="{= ?playerId }" />
<swon:Value arg:name="playerName" arg:value="{= ?playerName }" />
<swon:Value arg:name="playerCurrentTeam" arg:value="{=
?playerCurrentTeam }" />
<swon:Value arg:name="teamId" arg:value="{= ?teamId }" />
<swon:Value arg:name=\"playerFormerTeams\">
<ui:call arg:pft=\"{= former_team:1000 }\" ui:template=\"{=
int-spin:FormerTeamsByIdTemplate }\" ui:varName=\"pft_rs\">
<swon:RSArray arg:resultSet=\"{= ?pft_rs }\"/>
</ui:call>
</swon:Value>
</ui:forEach>
</ui:call>
</swon:Object>
</swon:Array>
</swon:Value>
How do I pass in the teamId result from the first query
(PlayersByTeamIdTemplate) to the second query
(FormerTeamsByIdTemplate)?
In the example above I've hard-coded it (former_team:1000 to
prove it works and it does (there is a prefix for "former_team").
I've tried things like arg:pft=\"{= former_team:?teamId }\" but
that doesn't work.
Have you also tried arg:pft="{= ?teamId }"? If that doesn't work,
could you send us the definition of the
int-spin:FormerTeamsByIdTemplate query so that I can see what else
could be mismatching?
Looking at the snippet above I also do wonder why the " characters
are sometimes escaped with \ and sometimes not...
Regards,
Holger
