Levels of interoperability • Semantic Level (Common Formats and Controlled Vocabularies) • Representational Level (XML, XSD) • Technical Level (Web Services) • 3. Interoperability options 3 and 4 • XSD / XML • Web Services (WSDL, SOAP, HTTP) • 5. Conclusion and questions

  3. 1. Information and metadata • Why is metadata important?- Information is not indexable- Information is not shareable • What is metadata?- Information about information- Structured data about data Human readable document jfhej e jwje wjwj eje je jejjjjej je jeje. eeje jej jejeejej e jejowoe j39ejj ejjq ejj wjwjej ejjw jjweje. jfhej e jwje wjwj eje je jejjjjej je jeje. eeje jej jejeejej e jejowoe j39ejj ejjq ejj wjwjej ejjw jjweje. jfhej e jwje wjwj eje je jejjjjej je jeje. eeje jej jejeejej e jejowoe j39ejj ejjq ejj wjwjej ejjw jjweje. jfhej e jwje wjwj eje je e rerew rewrewrewre re je jeje. eeje jej jejeejej e jejowoe j39ejj ejjq ejj wjwjej jejowoe j39ejj ejjq ejj wjwjej ejjw jjweje. jfhej e jwje wjwj eje je jejjjjej je jeje. eeje jej jejeejej e jejowoe j39ejj ejjq ejj wjwjej je jejjjjej je jeje. eeje jej jejeejej e jejowoe j39ejj ejjq ejj wjwjej ejjw jjweje jfhej e jwje wjwj eje je jejjjjej je jeje. eeje jej jejeejej e jejowoe j39ejj ejjq ejj wjwjej ejjw jjweje. jfhej e jwje wjwj eje je jejjjjej je jeje. eeje jej jejeejej e jejowoe j39ejj ejjq ejj wjwjej ejjw jjweje. jfhej e jwje wjwj eje je jejjjjej je jeje. eeje jej jejeejej e jejowoe j39ejj ejjq ejj wjwjej ejjw jjweje. jfhej e jwje wjwj eje je e rerew rewrewrewre re je jeje. eeje jej jejeejej e jejowoe j39ejj ejjq ejj wjwjej jejowoe j39ejj ejjq ejj wjwjej ejjw jjweje. jfhej e jwje wjwj eje je jejjjjej je jeje. eeje jej jejeejej e jejowoe j39ejj ejjq ejj wjwjej je jejjjjej je jeje. eeje jej jejeejej e jejowoe j39ejj ejjq ejj wjwjej ejjw jjweje jfhej e jwje wjwj eje je jejjjjej je jeje. eeje jej jejeejej e jejowoe j39ejj ejjq ejj wjwjej ejjw jjweje. jfhej e jwje wjwj eje je jejjjjej je jeje. eeje jej jejeejej e jejowoe j39ejj ejjq ejj wjwjej ejjw jjweje. jfhej e jwje wjwj eje je jejjjjej je jeje. eeje jej jejeejej e jejowoe j39ejj ejjq ejj wjwjej ejjw jjweje. jfhej e jwje wjwj eje je e rerew rewrewrewre re je jeje. eeje jej jejeejej e jejowoe j39ejj ejjq ejj wjwjej jejowoe j39ejj ejjq ejj wjwjej ejjw jjweje. jfhej e jwje wjwj eje je jejjjjej je jeje. eeje jej jejeejej e jejowoe j39ejj ejjq ejj wjwjej je jejjjjej je jeje. eeje jej jejeejej e jejowoe j39ejj ejjq ejj wjwjej ejjw jjweje jfhej e jwje wjwj eje je jejjjjej je jeje. eeje jej jejeejej e jejowoe j39ejj ejjq ejj wjwjej ejjw jjweje. jfhej e jwje wjwj eje je jejjjjej je jeje. eeje jej jejeejej e jejowoe j39ejj ejjq ejj wjwjej ejjw jjweje. jfhej e jwje wjwj eje je jejjjjej je jeje. eeje jej jejeejej e jejowoe j39ejj ejjq ejj wjwjej ejjw jjweje. jfhej e jwje wjwj eje je e rerew rewrewrewre re je jeje. eeje jej jejeejej e jejowoe j39ejj ejjq ejj wjwjej jejowoe j39ejj ejjq ejj wjwjej ejjw jjweje. jfhej e jwje wjwj eje je jejjjjej je jeje. eeje jej jejeejej e jejowoe j39ejj ejjq ejj wjwjej je jejjjjej je jeje. eeje jej jejeejej e jejowoe j39ejj ejjq ejj wjwjej ejjw jjweje Machine readable metadata Author = John SmithTitle = LMOsSubject = Biosafety

  8. Options 3 and 4Representational Level – XML • In order to be interoperable, each system needs to represent the information in the same way. • The de-facto standard to represent information is XML. XML is simple for both humans and computers to read.

  9. Options 3 and 4Representational Level – XML • Each document is individually encoded as an XML file Human readable document Machine readable metadata XML File jfhej e jwje wjwj eje je jejjjjej je jeje. eeje jej jejeejej e jejowoe j39ejj ejjq ejj wjwjej ejjw jjweje. jfhej e jwje wjwj eje je jejjjjej je jeje. eeje jej jejeejej e jejowoe j39ejj ejjq ejj wjwjej ejjw jjweje. jfhej e jwje wjwj eje je jejjjjej je jeje. eeje jej jejeejej e jejowoe j39ejj ejjq ejj wjwjej ejjw jjweje. jfhej e jwje wjwj eje je e rerew rewrewrewre re je jeje. eeje jej jejeejej e jejowoe j39ejj ejjq ejj wjwjej jejowoe j39ejj ejjq ejj wjwjej ejjw jjweje. jfhej e jwje wjwj eje je jejjjjej je jeje. eeje jej jejeejej e jejowoe j39ejj ejjq ejj wjwjej je jejjjjej je jeje. eeje jej jejeejej e jejowoe j39ejj ejjq ejj wjwjej ejjw jjweje <authority> <header> <id>A0001</id> <date>2006-05-22</id> </header> <country refid=“my” /> <title>Agriculture Dep.</title> <phone>555-555-1212</phone></authority> CountryMalaysia OrganizationAgriculture Dep.

  10. Options 3 and 4Representational Level – XML • The structure of the XML corresponds to the common format. <authority> <header> A0001 <id> </id> <date> 2006-05-22 </date> </header> <country refid = "my" refid = my /> </title> <title> Agriculture Dep. <phone> </phone> 555-555-1212 <Element> <Attribute> </authority> Value

  11. Example file: authorityA0001.xml Options 3 and 4Representational Level – XML <?xml version="1.0" encoding="UTF-8"?> <authority> <header> <id>A0001</id> <date>2006-05-22</id> </header> <country refid="my" /> <title>Agriculture Dep.</title> <phone>555-555-1212</phone></authority> • XML looks like HTML • The structure of the XML corresponds to the common format. • The common format is defined using a XML Schema (XSD)

  12. Options 3 and 4Representational Level – XML Step 1 – Prepare XML Step 2 – Register XML Encode document in XML This step is common to bothoptions 3 and 4. Register XML documentin the Central Portal of the BCHusing either option 3 or 4 jfhej e jwje wjwj eje je jejjjjej je jeje. eeje jej jejeejej e jejowoe j39ejj ejjq ejj wjwjej ejjw jjweje. jfhej e jwje wjwj eje je jejjjjej je jeje. eeje jej jejeejej e jejowoe j39ejj ejjq ejj wjwjej ejjw jjweje. jfhej e jwje wjwj eje je jejjjjej je jeje. eeje jej jejeejej e jejowoe j39ejj ejjq ejj wjwjej ejjw jjweje. jfhej e jwje wjwj eje je e rerew rewrewrewre re je jeje. eeje jej jejeejej e jejowoe j39ejj ejjq ejj wjwjej jejowoe j39ejj ejjq ejj wjwjej ejjw jjweje. jfhej e jwje wjwj eje je jejjjjej je jeje. eeje jej Internet XML XML XML XML XML BCH Crawler (option 3) or BCH Web Service (option 4) BCH DB http://bch.biodiv.org

  13. Options 3 and 4Representational Level – XML • Review • In order to be interoperable systems need to represent the information the same way • XML represents the information • XML Schema describes the common format. XSD files are provided by the CBD Secretariat. They form basis for exchange between disparate systems

  14. Option 3Pull – BCH Crawler • Now that we have an XML file containing the information to register, lets continue with option 3.

  15. Option 3Pull – BCH Crawler Document Apache / IIS Web Server Internet XML /index.html /… /export/decision01.xml/export/decision02.xml/export/decision03.xml/export/decision04.xml … e.g. Law XML XML BCH Crawler Robot XML XML Steps 1. Prepare the XML file (e.g. Decision Under AIA) 2. Place the XML file the web server The BCH Crawler Robot will take care of the rest. It will download the file a register it into the BCH. XML XML XML XML BCH DB http://bch.biodiv.org

  16. What are Web Services? A family of specifications that layers on XML stack Formalizes description of messages based on schema elements Option 4Push – BCH Web Service WSDL SOAP Details of transmission over HTTP XML Schema Describes the structure XML Represents the information

  17. Option 4Push – BCH Web Service SOAP Message Internet SOAP Envelope e.g. Law XML HTTP/HTTPS XML Your WS/SOAP library will do that BCH WS Steps 1. Encode document in XML 2. Envelope the XML in a SOAP message 3. Send the SOAP message through HTTP/HTTPS XML XML XML XML BCH DB http://bch.biodiv.org

  18. Conclusion • No solution is better than others • The best option depends on • the needs • how much information you have and; • how often you need to update your information • the assets • existing databases • platform used (windows, unix, etc.) • actual and future resources • IT knowledge • financial resources • Making the right choice is primordial
