9 FishBase and Web Services 1. FishBase offers web services and 2. makes use of web services as well - web data syndication - both XML and non-xml format

10 What is a web service? An entire web site and every single page in it can be considered individually as a web service. An XML Web Service utilizes XML and optionally other standards used to define an efficient way to describe the Web Service and talk to other Web Services. Simple XML web service = URL + HTTP + XML Complex XML web service = URL + HTTP + XML + (SOAP + WSDL + UDDI)

11 FishBase Web Service A typical sample of a web service using XML data format Requests for fish info The web user can either be: 1. end-user 2. data provider that gathers information on available web services in the internet

12 XML Web Services Offered by FishBase Species Summary FishBase offers data in XML format so others can readily use these data in their own systems Point Data Common Names -in XML + XSL -URL driven

13 Country-related XML Web Services Offered by FishBase: Species Lists for a country: Biodiversity: Uses: 1. All fishes 1. Commercial 2. Freshwater 2. Species used in Aquaculture 3. Marine 3. Species of potential use in aquaculture 4. Introduced 4. Aquarium species being exported live 5. Endemic 5. Species with potential for aquarium trade 6. Threatened 6. Game fishes 7. Dangerous 7. Fish Loss 8. Reef-associated 9. Pelagic 10. Deep-water

14 Country web sites can then incorporate FishBase data into their pages as if it is their own. All this is possible now thanks to XML... CHECKLIST FRESH - WATER MARINE INTRODUCED e.g. Philippine List of Species ENDEMIC

15 Web Services Used by FishBase a. Fish Occurrence (Point) Data b. Data Maps and Summaries c. Language Translations

16 Fish Occurrence Data Example: Esox lucius FishBase = 292 Provided by TSA = 299 Combined Total: FB+TSA = 591 records

17 Web Data Syndication (FishBase + TSA) N = 1661 TSA (292 records) (299 records) - reads XML file from TSA - combines data with FishBase - displays final page with 591 records to user Program

18 Data Representation: Maps and Data Summary (using KGS server) Point Map for Esox lucius (n = 591 records) Sample Environmental Data Summary (n = 591 records)

19 SYSTRAN Translation Service: non-xml FishBase now uses SYSTRAN to translate selected fields in FishBase on the fly (Distribution, Diagnosis, Biology and other fields)

20 FishBase as data provider and data portal

21 FishBase & Open Source --- Implementation Status Developed applications written in PHP (NAEIS, Collection Search Portal, Species 2000) Exploring MySQL, PostgreSQL as possible database systems Apache Web Server being used in some FishBase servers.

22 (PHP Implementation) NAEIS (National Aquatic Ecosystem Information System) is a prototype site-specific database module linked to FishBase Species 2000: list of all known species in the planet A search portal for DiGIR providers (Distributed Generic Information Retrieval); good example of a distributed architecture

23 Options on using FishBase 1. Using the FishBase web site 2. Developing an independent site using data subsets of FishBase 3. URL links to FishBase 4. Using FishBase data thru web services (data syndication)

24 1. Using the FishBase web site

25 Fishery Trophic Level Historical Profile Fishery Trophic Analysis (Time Periods) Species Identification Key FishBase the Analytical Tools Web Tools useful In Developing Biodiversity Information Systems & Web Sites Fish Catch Length Frequency Analysis Wizard Species Key Facts Page (Species, Population Parameter Estimates)

26 Phil Production Prototype (P3) is a subset of FishBase that pertains only to the species found in the Philippines. 2. Developing an independent site using data subsets of FishBase National Aquatic Ecosystem Information System (NAEIS) is a prototype site-specific database module linked to FishBase. Species 2000, patterns some of its tables to FishBase, namely: Species, Common names, References and Distribution. A special search page for 'FishBase with special emphasis on the Americas. All lists are restricted to names, species, families, countries/islands, and ecosystems of the Americas.

27 Specific application of FishBase: Developing National Aquatic Information Systems Country Code Bangladesh 050 Cambodia 116 Iran 364 Malaysia 458 Philippines 608 Vietnam 704

28 3. URL links to FishBase URL = Uniform Resource Locator All items under Information by Country / Island can also be accessed via URL s like so: c_code=608&group=allfishes

29 Values for the group URL parameter: BIODIVERSITY USES All fishes = allfishes Commercial = commercial Freshwater = freshwater Aquaculture = aquaculture Marine = marine Aquarium trade = aquarium Introduced = introduced Game fishes = sports Endemic = endemic FAO Aquaculture = fao_aqua Threatened = threatened FAO catches = fao_catch Dangerous = dangerous ICES catches = ices_catch Reef-associated = reef Fish loss = fishloss Pelagic = pelagic Deep-water = deepwater TOOLS MISCELLANEOUS Identification keys = idkeys Country info. = information Field guide = fieldguide FAO profile = faoprofile Occurrences = speciesoccurrence ReefBase profile = reefbase Type localities = typelocal Treaties & Conv. = treaties References = references Collaborators = collaborators Ecopath data = ecoparam Fish stamps = fishstampscountry Common names = commonnames Public aquariums = publicaquariums

30 You can then create the other URL s in this manner: c_code=608&group=allfishes c_code=608&group=freshwater c_code=608&group=marine c_code=608&group=introduced c_code=608&group=endemic

31 These URL s will then produce country species lists in FishBase:

32 4. Using FishBase data thru web services (data syndication)

33 Accessing regular web pages vs. web services: This is the way to access web pages in FishBase via URL links: c_code=608&group=allfishes Now, this is the way to access web services in FishBase via URL links: c_code=608&group=allfishes An agreement: when accessing HTML; you are accessing web pages when accessing XML; you are accessing web services

34 How was it done: PHP $data = implode("",file(' ColdFusion <cfhttp url=" c_code=608&group=introduced" timeout="60" method="get"> </cfhttp> <cfset data = #cfhttp.filecontent#> ASP var objsrvhttp; objsrvhttp = Server.CreateObject ("MSXML2.ServerXMLHTTP"); objsrvhttp.open ("GET"," c_code=608&group=introduced ", false); objsrvhttp.send (); Response.ContentType = "text/xml"; data = objsrvhttp.responsexml.xml;

35 Lessons Learned: Summary - Web data syndication is a good and practical option for data providers like FishBase if local data are not enough to make an impact to users. - Distributed processing is a realization that projects can work together, complement each other and be of better service to users. - The web is rich with tools and methodologies; don t re-invent the wheel but adopt standards to achieve global acceptance and room for change. - XML as data exchange format is here to stay - Open Source software should be investigated as options.
