| - In general, the {{search}} operation requires access to all semantic annotations to find matching resources. For example, consider a search expression {{A and B}}, i.e., a resource must contribute to both concept {{A}} and concept {{B}}. To find appropriate matches for this search term, the algorithm must look for annotations that explicitly state {{A and B}} as well as those that state only {{A}} and only {{B}} (which taken together make {{A and B}}). Note that an annotation that states only {{A}} may be in one repository, while an annotation that states {{B}} may be in another. Thus, for remote searches, the {{search}} algorithm must gather and consider all remote annotations to find matching resources. The {{search}} operation is inherently centralized because of this situation. |
