Start to Create and Validate!
The OLIF DTD can already be used to create entries with a structure editor
validate data

Design Goals and Decisions
1. Stay close to the prose description Strive for identifical naming in both description and formalization
2. Provide legible, consistent and clear formalization Model identical state-of-affairs the same way; refrain from surrogate
representations; uniform representation of data categories as elements
3. Support maintenance and customization Modularize overall solution and write extensive documentation
4. Allow easy implementation Refrain from use of very recent technologies (e.g. Xlink and Resource
Description Format)
5. Advance quickly Postpone time-consuming issues (e.g. non-compromising solution to free
order of elements and alternative content)
6. Use flexible representation formalism Work with DTD rather than XML schema

Suffixes for Parameter Entities
1. .att for attributes <!ENTITY % creaTool.att "CreaTool CDATA #REQUIRED" >
2. .pcd.mix for PCDATA content models
<!ENTITY % company.pcd.mix "#PCDATA" >
3. .olif.fix for list of mandatory OLIF values<!ENTITY % adminStatus.olif.fix "#PCDATA" >
4. .olif.pending for list of OLIF values pending approval
<!ENTITY % semReading.olif.pending.user.ext "#PCDATA %semReading.user.ext;" >
5. .user.ext for user extensible content models
<!ENTITY % ptOfSpeech.olif.fix.user.ext "#PCDATA %ptOfSpeech.user.ext;" >
As indicated in the examples, suffixes can be concatenated.

Data Category Values as XML
Creation and checking of OLIF is facilated by machine-readable representations (XML) of all allowed or recommended values
![Page 8: Does It Fit? Review of the Proposal for OLIF (version 2) DTD Christian Lieske SAP AG - GBU Application Integration – MultiLingual Technology](https://reader035.vdocument.in/reader035/viewer/2022062618/55148785550346d36e8b4d04/html5/thumbnails/8.jpg)

Example Sections – contentInfo
The contentInfo element explicitly states which choices have been made wrt. representation of content (e.g. retention of quotation marks); in addition, it can state default values for certain data categories (DCs)

Special Mechanisms
For user extensions, 2 mechanisms exist:
1. DTD customization
<!ENTITY % ptOfSpeech.olif.fix.user.ext "#PCDATA %ptOfSpeech.user.ext;" >
<!ENTITY %ptOfSpeech.user.ext "" >
2. Data category specifications
