			<content:encoded><![CDATA[<h4>More &#8220;Open&#8221; Social</h4>
<p>Die <em>Open Social Foundation</em> plant die zweite Version des Social-Widget-APIs und will sich diesmal noch mehr an bestehenden Standards orientieren:</p>
<blockquote><p>Areas of exploration include but are not limited to:<br />
- Aligning with Activity Streams, OStatus, SWAT0, and OEmbed<br />
- Deprecating or wholesale removal of little used features.<br />
- Removing ambiguity and tightening up the spec.</p></blockquote>

<h4>Deutschland entdeckt OExchange</h4>
<p>StudiVZ und XING ver-oexchangen ihre Share-Buttons (und unterst&#252;tzen damit &#252;brigens auch <a href="http://tools.ietf.org/html/rfc5785">/.well-known/</a> und <a href="http://tools.ietf.org/html/draft-hammer-hostmeta-13">host-meta</a>):</p>

<h4>Portable Gravatar Contacts</h4>
<p>Seit einiger Zeit lassen sich &#252;ber Gravatar auch Profilinformationen (im <em>Portable Contacts</em> Format) abrufen:</p>
<blockquote><p>We use Portable Contacts to format our profile data whereever possible, so see the PoCo spec for more details on the structure of the response.</p></blockquote>

<p>&#8230;und das sollte doch wiederum Grund genug sein seine Seite sofort OpenID tauglich zu machen, nachher wissen die armen Menschen gar nicht wohin mit ihrer OpenID&#8230;</p>
<p>Spa&#223; beiseite&#8230; nat&#252;rlich besteht generell nicht das Problem an fehlenden OpenID-Providern, aber die Ank&#252;ndigungen von Microsoft und Google sollten bisherigen Zweifeln dennoch signalisieren, dass OpenID der aktuelle <em>de facto</em> Standard f&#252;r <em>Single Sign-On</em> im Web sein d&#252;rfte.</p>

			<content:encoded><![CDATA[<p>Dass sich das <a href="http://portablecontacts.net/draft-spec.html#structure">Portable Contacts Schema</a> trotz der Aussage:</p>
<blockquote cite="http://portablecontacts.net/draft-spec.html#anchor5"><p>Third, we&#8217;re reusing existing standards wherever possible, including vCard, OpenSocial, XRDS-Simple, OAuth, etc.</p></blockquote>
<p>von dem des <a href="http://microformats.org/wiki/jcard">v/hCard Schema</a> unterscheidet, habe ich ja schon <a href="http://notizblog.org/2008/08/08/portable-contacts-schicker-als-ich-dachte/#portable-microformats">vor einigen Wochen erl&#228;utert</a>:</p>
<blockquote><p>Schade dass die vCard nicht zu 100% &#252;bernommen wurde… sonst h&#228;tte man ohne gr&#246;&#223;ere &#196;nderungen auch die JSON-Serialisierte hCard (jCard) in den Prozess integrieren k&#246;nnen. Spannend w&#228;re es vor allem f&#252;r Services wie Twitter, die das Freundesnetzwerk sowieso mit hCards auszeichnen.</p></blockquote>
<p>Aber das sch&#246;ne an Standards ist, dass sie sich ohne gro&#223;en Aufwand in andere transformieren lassen. <a href="http://lab.madgex.com/">Magdex</a> (die Firma hinter <a href="http://lab.madgex.com/ufxtract/">UfXtract</a> und <a href="">OAuth.net</a>) bietet eine <a href="http://lab.madgex.com/portablecontacts/">Reihe dieser Transformatoren</a> um z.B. <a href="http://lab.madgex.com/portablecontacts/hcardtopoco.aspx">hCards</a>, <a href="http://lab.madgex.com/portablecontacts/hcardxfntopoco.aspx">hCards + XFN</a> oder <a href="http://lab.madgex.com/portablecontacts/hresumetopoco.aspx">hResumes</a> in das <em>Portable Contacts</em> &#8211; Format zu bringen.</p>
<p>&#8230;jetzt das ganze nur noch mit <a href="http://portablecontacts.net/draft-spec.html#anchor10">OAuth</a> sch&#252;tzen und fertig ist die <em>Portable Contacts</em> API <img src='http://notizblog.org/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /> </p>

<p>&#8230;habe ich endlich auch eine <a href="http://portablecontactsdemo.janrain.com/">funktionierende Demo</a> im Web gefunden. Notwendig f&#252;r die Testanwendung sind ein <a href="https://www.myopenid.com/signup">myOpenID Profil</a> und ein <a href="https://www.plaxo.com/signup">Plaxo-Account</a>.</p>
<p>Zuerst muss man &#252;ber den <a href="https://www.myopenid.com/settings_pcp">myOpenID Einstellungen</a> Plaxo als seinen <em>Portable Contacts &#8211; Provider</em> angeben,</p>
<p><img src="http://notizblog.org/wp-content/uploads/2008/09/openid-porc.jpg" alt="openid-porc.jpg" width="480" height="200" class="aligncenter" /></p>
<p>sich mit seiner OpenID an der Demoseite anmelden,</p>
<p><img src="http://notizblog.org/wp-content/uploads/2008/10/openid-with-portable-contacts-demo.png" alt="" width="480" height="320" class="aligncenter" /></p>
<p>den Zugriff auf die eigenen Daten gew&#228;hren</p>
<p><img src="http://notizblog.org/wp-content/uploads/2008/10/plaxo-pulse.jpg" alt="Plaxo Pulse.jpg" border="0" width="480" height="200" class="aligncenter" /></p>
<p>und die Demo-Anwendung bekommt meine Kontakte &#252;bermittelt.</p>
<p><img src="http://notizblog.org/wp-content/uploads/2008/10/openid-with-portable-contacts-demo.jpg" alt="OpenID with Portable Contacts Demo.jpg" width="480" height="484" class="aligncenter" /></p>
<p>Im besten Fall laufen diese Schritte v&#246;llig automatisch ab und der Anwender hat nicht mehr zu tun als seine Einverst&#228;ndniserkl&#228;rung per Knopfdruck zu geben. Ein sch&#246;ner Anwendungsfall f&#252;r dieses Beispiel w&#228;re z.B. eine OpenID-Neuanmeldung bei einer Community mit anschlie&#223;endem Import aller Kontakte.</p>
<p>Was ich an diesem Beispiel au&#223;erdem sehr sch&#228;tze ist, dass JanRain die <em>Portable Contacts API</em> in seinen OpenID-Provider integriert hat ohne sie wirklich integriert zu haben&#8230; Der Fokus von myOpenID bleibt weiterhin auf OpenID und die <em>Portable Contacts</em> Anfragen werden <em>lediglich</em> <a href="http://portablecontacts.net/draft-spec.html#discovery">&#252;ber XRDS-Simple</a> an z.B. Plaxo weiterdelegiert.</p>
<p>So zentral kann dezentral sein <img src='http://notizblog.org/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /> </p>

			<content:encoded><![CDATA[<p>Plaxo setzt voll auf den neuen (<a href="http://notizblog.org/2008/09/11/portable-contacts-der-neue-grosse-building-block/">gro&#223;en?</a>) Building-Block <em>Portable Contacts</em> (<a href="http://blog.plaxo.com/archives/2008/09/portable_contac_1.html">Portable Contacts is now Plaxo&#8217;s primary API</a>):</p>
<blockquote cite="http://blog.plaxo.com/archives/2008/09/portable_contac_1.html"><p>We&#8217;ve been early adopters and evangelists for several of these building blocks, including OpenID, OAuth, OpenSocial, and microformats. And recently we&#8217;ve also helped lead the charge to build another key piece of the &#8220;open stack&#8221;: a common API standard for accessing address book, profile, and friends-list data called &#8220;Portable Contacts&#8221;.</p></blockquote>
<p>Die <a href="http://www.plaxo.com/api">API-Section von Plaxo</a> weist jetzt eine beachtliche Anzahl an offenen Standards auf:</p>
<blockquote cite="http://blog.plaxo.com/archives/2008/09/portable_contac_1.html"><p>We&#8217;ve revamped Plaxo&#8217;s developer section to focus primarily on the open building blocks we&#8217;re using. Starting now, developers should consider OAuth and Portable Contacts the primary way to access profile, address book, and pulse connections data from Plaxo.</p></blockquote>
<p>Vorbildlich!</p>
<p>Eine weitere Ank&#252;ndigung (via Newsletter) kommt vom OpenID-Provider <a href="http://www.myopenid.com">myOpenID</a>, der (in Person von <a href="http://brianellin.com/">Brian Ellin</a> von JanRain) ja schon auf dem <a href="http://notizblog.org/2008/09/11/portablecontacts-hacks/">PortableContacts Hackathon</a> eine umfassende Demo zum besten geben konnte.</p>
<blockquote><p>Portable Contacts is an emerging standard for transferring profile data and social connections across websites.  Look for upcoming support of this new standard in myOpenID!</p></blockquote>
<p>Dieses Feature w&#252;rde mich dann doch davon abhalten <a href="http://notizblog.org/2008/09/17/wordpress-wird-openid-provider/">mein eigener OpenID-Provider</a> zu sein <img src='http://notizblog.org/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /> </p>

			<content:encoded><![CDATA[<p><a href="http://radar.oreilly.com/davidr">David Recordon</a> stellt auf <a href="http://radar.oreilly.com">O&#8217;Reilly &#8211; Radar</a> zwei der spannendsten Ergebnisse des gestrigen <a href="http://upcoming.yahoo.com/event/1078491/">PortableContacts Hackathon (bei Six Apart)</a> vor:</p>
<blockquote><p>Joseph Smarr and <a href="http://kevinmarks.com/">Kevin Marks</a> of Google hacked together a web transformer that integrates Microformats, vCard, and the Portable Contacts API.  Given Kevin&#8217;s homepage which is full of Microformats, they&#8217;ve built an API that extracts his profile information from hCard, uses a public API from Technorati to transform it to vCard, and then exposes it as a Portable Contacts API endpoint.  Not only does this work on Kevin&#8217;s own page, but his Twitter profile as well which contains basic profile information such as name, homepage, and a short bio.</p></blockquote>
<p>Ein sch&#246;nes Beispiel was man mit semantisch ausgezeichneten Informationen machen kann und dass Microformats eben auch (ohne viel Aufwand und mit ein bisschen Transformation) in <em>h&#246;herwertige</em> APIs integriert werden k&#246;nnen&#8230; also keine hCard wurde umsonst geschrieben <img src='http://notizblog.org/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /> </p>
<blockquote><p><a href="http://brianellin.com/">Brian Ellin</a> of JanRain has successfully combined OpenID, XRDS-Simple, OAuth, and the Portable Contacts API to start showing how each of these building blocks should come together.  Upon visiting his demo site he logs in using his OpenID.  From there, the site discovers that Plaxo hosts his address book and requests access to it via OAuth.  Finishing the flow, his demo site uses the Portable Contacts API to access information about his contacts directly from Plaxo.  End to end, login with an OpenID and finish by giving the site access to your address book without having to fork over your password.</p></blockquote>
<p>Dazu brauche ich nicht mehr sagen, als: Implementieren! Sofort und &#252;berall <img src='http://notizblog.org/wp-includes/images/smilies/icon_wink.gif' alt=';)' class='wp-smiley' /> </p>

			<content:encoded><![CDATA[<p>Anl&#228;sslich des gestrigen <a href="http://upcoming.yahoo.com/event/1078491/">PortableContacts Hackathon bei Six Apart</a> (<a href="http://therealmccrea.com/2008/09/11/live-from-the-portablecontacts-hackathon/">Impressionen</a>) und dem heutigen <a href="http://upcoming.yahoo.com/event/1005694/">PortableContacts-Summit bei myspace</a> besch&#228;ftigt sich die <a href="http://www.thesocialweb.tv/blog/2008/09/episode-9-a-big.html">aktuelle SocialWeb.TV</a> &#8211; Folge fast ausschlie&#223;lich mit dem neuen &#8220;Building-Block&#8221;.</p>
<p><object type="application/x-shockwave-flash" style="width:437px; height:288px;" data="http://www.viddler.com/player/2fd78fa9/"><param name="movie" value="http://www.viddler.com/player/2fd78fa9/" /><param name="allowScriptAccess" value="always" /><param name="allowFullScreen" value="true" /><param name="wmode" value="transparent"/></object></p>
<p>Zwar ist die <a href="http://www.thesocialweb.tv/blog/2008/08/episode-5-the-p.html#comment-1140014">Kritik von Stephen Paul Weber</a> (der <a href="http://diso-project.org/">DiSo</a> Code-Maschine):</p>
<blockquote><p>Portable Contacts is an open spec &#8211; but it&#8217;s a bit of a stretch to call something a few days old and unimplemented as yet a &#8220;standard&#8221;.</p></blockquote>
<p>nicht ganz abwegig aber Joseph Smarr (Plaxo), der Initiator von <a href="http://portablecontacts.net">Portable Contacts</a>, &#252;berzeugt mit einigen Argumenten warum sich das bald &#228;ndern k&#246;nnte. Portable Contacts baut ausschlie&#223;lich auf offenen Standards (<a href="http://notizblog.org/2007/10/05/oauth-core-10-final-draft/">OAuth</a>, <a href="http://notizblog.org/2008/05/05/xrds-simple-eine-einfuehrung/">XRDS-Simple</a>, JSON) auf und nutzt die gleiche Vorgehensweise wie die <a href="http://code.google.com/apis/opensocial/docs/0.8/restfulspec.html">OpenSocial RESTful-API</a>. Diese Eigenschaften machen neue Code-Libraries fast &#252;berfl&#252;ssig (da <abbr title="PortableContacts">PC</abbr> eigentlich nur bestehende Standards sinnvoll verbindet) und gestalten die Implementierung, bei schon implementierter <abbr title="Open Social">OS</abbr> RESTful-API, relativ einfach.</p>
<p>Glaubt man der Aussage von Joseph im Video, soll der neue Standard noch bis Ende des Jahres nutzbar gemacht werden. Bei den m&#246;glichen Implemtoren h&#228;lt er sich zwar bedeckt, aber wenn auch &#8220;nur&#8221; die beiden oben genannten Veranstalter (<a href="http://www.sixapart.com">Six Apart</a> und <a href="http://www.myspace.com">myspace</a>) und Plaxo diese Schnittstelle umsetzen kann man (trotz Stephens Kritik) wirklich schon fast von einem <em>Open Standard</em> sprechen.</p>
<p>Bin gespannt auf die Ergebnisse des heutigen Summits&#8230;</p>
