Creating interfaces XML & XSL review Voice. XML: grammar Homework: postings, presentation, study guide

XML General format for data. Intended for use between people and applications and between applications and applications. • XSLT: language (itself XML format) for transforming XML, – one use being XML to HTML. The resulting HTML can use Java. Script. – XML to WML – XML to Voice. XML (probably less common, but this use could grow)

XML • Used ‘server side’ with php or asp or Cold. Fusion or older technologies: cgi/perl • Used with/by Flash • Used ‘client side’ by Java. Script • Used with 'Web services'

Preview • Next Fall, new course on Java and connections (title not set) • Peter Ohring • probably evening • upper-level math/cs elective

XML • format for holding content (independent of formatting and use) • Not the only one! Consider – relational databases – linked lists – general graphs (nodes with any number of links, possibly cycles) –?

"XML Languages" • XSLT • WML • Voice. XML • There are now also XML specifications for books, purchase orders, math, etc.

Voice. XML Grammars • Use / study grammars in Tellme studio • Note: GRXML, alternative form of grammar that is an XML format will probably replace GSL, currently used by Tellme • Look up: bargein, n-best • Specifying numeric keys: dtmf • Setting multiple values

Grammars • • • Parentheses indicate ‘and’ (sequence of words) Square brackets (within an option) indicate ‘or’ ? Indicates optional: zero or 1 occurrence * indicates any number of occurrences + indicates one or more occurrences [(math ? (computer science))] accepts math computer science [purchase pace] accepts purchase pace

Questions • Give a grammar that accepts "Tom", "Dick", or "Harry" • Give a grammar that accepts "Bill Clinton", "Hilary Clinton", "President Clinton" • Give a grammar that would distinguish between the 41 st president and the 43 rd president.

DTMF • The grammar mode default setting is both voice and dtmf. • dtmf-1 means to accept caller hitting 1 key • Use grammar tools in My Studio for help generating the keys to represent letters

<? xml version="1. 0" ? > <vxml version="2. 0"> <form> <field name="answer"> <grammar type="application/x-gsl" > <![CDATA[ [ [yes dtmf-1] {<answer "yes">} [ no dtmf-2 ] {<answer "no">} ] ]]> </grammar> <prompt count="1"> Say yes or no </prompt> <prompt count="2"> Press 1 or say yes or press 2 or say no. </prompt> <catch event="noinput nomatch"> <reprompt/> </catch> <filled> <audio>You said <value expr="answer"/></audio> </filled> </field> </form> </vxml>

Letter correspondences • In My Studio, click on Grammar Tools and then DTMF and the system will generate sequences (and let you know if there are problems) • Here are 3 letter sequences for these two choices: 1. dtmf-6 dtmf-2 dtmf-8 math 2. dtmf-6 dtmf-3 dtmf-9 new media

Setting multiple values [(math ? computer)] {<major “math"> <building “NS">} [(new media)] {<major “nm"> <building “Music">}

Tellme • My. Studio: 1 -800 -555 -VXML You need to give 5 digit plus 4 digit pin • For all of us to use your project, we need – you to upload all files to your rachel account (or some other website) – you to tell us the URL of the xml file

Homework • Postings (on other people’s projects) • Projects: Be prepared to give demonstration and turn in (hardcopy) description and, – if you are doing Voice. XML, your URL – If doing a Web page, the URL • Review guide to final
