Improving Code Validity Metrics for Italian Public Institutions' Websites

Italian regulations mandate the use of DTD strict codes, but 57% of websites fail to comply. This study proposes a novel approach to evaluate errors in code validity, strictness, and markup quality across different DTDs, with the aim to enhance website compliance. Through experimental assessment and defining Error Springing Up Rate (ESUR), the study offers a strategy to improve web coding standards.

  1. Problem addressed HTML 4.01 strict, XHTML 1.0 strict or superior are allowed by the Italian regulations Distinct dominions not easily comparable 43% of Italian Public institutions homepages are declared DTD strict Meaningful synthesis about code validity cannot simply exclude 57% of monitored Web contents 1

  2. Strategy We issued an experimental approach, thereby defining a metrics to: quantify expected errors on a target DTD from a different one; evaluate 3 properties: validity, strictness, markup quality. Such a metrics can be generalized to: approach a more general instance about comparing documents with different DTDs. 2

  3. We defined the expected number of errors for a given DTD as: We called the couple: (x'i, x''i) Errors Springing Up Rate(ESUR). They are computed, based on a wide sample of sites according to a couple of weighted averages on errors about DTDs. a sample of 1000 Web sites has been used to compute x'i and x''i as follows: Strategy (2) 3
