Creating Arrays of structured fields with XMP 3.2 SDK

-

i'm trying adobe xmp sdk 3.2 operate in same manner the<br />imetadataaccess interface in indesign / incopy.<br /><br />1. consider following snippet of indesign sdk code.<br /><br />foo( imetadataaccess * mymeta )<br />{<br />pmstring regprefix;<br />pmstring ns( "http://my.namespace.com/test/" );<br />pmstring nspfx( "myns" );<br /><br />mymeta->registernamespace( ns, nspfx, regprefix );<br /><br />pmstring path( "testpath" );<br /><br />// create new bag array<br /><br />mymeta->appendarrayitem( ns, path, emptystr, metadata_bag, metadata:kpropvalueisstruct );<br />.....<br />}<br /><br />this generate following entry in xmp.<br /><br /><rdf:description rdf:about="" xmlns:myns="http://my.namespace.com/test/"><br />         <myns:testpath><br />            <rdf:bag><br />               <rdf:li rdf:parsetype="resource"><br />               </rdf:li><br />            </rdf:bag><br />         </myns:testpath ><br />      </rdf:description><br /><br />2. consider following using xmp sdk<br /><br />foo2( sxmpmeta * mymeta )<br />{<br />std::string registeredprefix("");<br />pmstring emptystr("");<br /><br />mymeta->registernamespace( "http://my.namespace.com/test/" , "myns", &registeredprefix );<br /><br />try<br />{<br />mymeta->appendarrayitem( "http://my.namespace.com/test/", "testpath", kxmp_propvalueisarray, "" );<br />.....<br />}<br />catch( ... )<br />{<br /><br />}<br />}<br /><br />this generate following entry in xmp.<br /><br /><rdf:description rdf:about="" xmlns:myns="http://my.namespace.com/test/"><br />         <myns:testpath><br />            <rdf:bag><br />               <rdf:li/><br />            </rdf:bag><br />         </myns:testpath ><br />      </rdf:description><br /><br />i.e rdf:parsetype="resource" entry missing generated xmp.<br /><br />this causes problems adding items array with<br /><br />mymeta->setstructfield( "http://my.namespace.com/test/", "testpath[1]", "http://my.namespace.com/test/", "name1", "value1" );<br /><br />i exception raised. ( setstructfield works if rdf:parsetype="resource" entry in place ).<br /><br />so question how rdf:parsetype="resource" tag appear in rdf:li element using xmp 3.2 sdk??<br /><br />my aim create xmp this<br /><br /><rdf:description rdf:about="" xmlns:myns="http://my.namespace.com/test/"><br />         <myns:testpath><br />            <rdf:bag><br />               <rdf:li/><br />                  <myns:id>1111</myns:id><br />                  <myns:name>albert</myns:name><br />               </rdf:li><br />               <rdf:li/><br />                  <myns:id>1112</myns:id><br />                  <myns:name>fred</myns:name><br />               </rdf:li><br />            </rdf:bag><br />         </myns:testpath ><br />      </rdf:description><br /><br />tia.<br />mike.

solved now!

mymeta->appendarrayitem( "http://my.namespace.com/test/", "testpath", kxmp_propvalueisarray, "" );

should

mymeta->appendarrayitem( "http://my.namespace.com/test/", "testpath", kxmp_propvalueisarray, nil, kxmp_propvalueisstruct );

hello, first post asking in forum patient if dont correctly   well, im trying make robot evades obstacles , uses interrupts in order distances. ive used flexitimer2 run void function each 5ms, problem whe try verify program says me there error in use of flexitimer.    code: [select] flexitimer2::set(1, 1.0/1000, rastreodistanciamin()); i copy code below, please can tell error , how solve it, ive been loking dont know do. thank you code: [select] #include <flexitimer2.h> #include <servo.h> //motor a int ena = 7; int in1=6; int in2 = 5; //motor b int in3=11; int in4=10; int enb=9; servo cabeza; //hc-sr04 device int echo = 13; int triger = 12; //it use hc-sr04 determine , return distance in front of him int calculodistancia(){   volatile int tiempo;   volatile int distancia;   digitalwrite(triger,low); /* por cuestión de estabilización del sensor*/   delaymicroseconds(5);   digitalwrite(triger, high); /* envío del pulso ultrasónico*/   delaymicroseconds(10);   tiem
