This orchestration scrap the content of a given folksonomy (aka tags) and looks over usual Web 2.0 pictures repository (Picasa & Flickr) for images which match.

It returns a set (of given size) of URL to reach those images, taking care of shuffling the image set to simulate an indeterministic behaviour (seeing always the same pictures is kinda boring …)

• Partners:
  • PicasaWrapper
  • FlickrWrapper
  • PictureSet

• BPEL Code: ImageScraper.bpel

The orchestration expect a tags query (xsd:string, multiples tags separated by commas) and a given size to truncate the result set.

<xsd:complexType name="ImageScrapperIn">
  <xsd:sequence>
    <xsd:element name="tags" type="xsd:string"/>
    <xsd:element name="size" type="xsd:int"/>
  </xsd:sequence>
</xsd:complexType>
<xsd:element name="ImageScrapperRequest" type="tns:ImageScrapperIn"/>

The orchestration answers a set of URLs as response message:

<xsd:complexType name="ImageScrapperOut">
  <xsd:sequence>
    <xsd:element name="url" type="xsd:anyURI" maxOccurs="unbounded"/>
  </xsd:sequence>
</xsd:complexType>
<xsd:element name="ImageScrapperResponse" type="tns:ImageScrapperOut"/>
