4. Q: How to make sure that all of material code is correct in case that all users can add their materials information?
A: There are 3 ways in UMCS to keep the correctness of material codes. First, wrong codes do not disturb usage of material code. User only select correct material code for material referring. Second, User could inform UMCS administrator by e-mail if he finds a wrong code. The administrator will check and correct the error. Third, only paid users can add a large number of codes. Free user can only add limited quantity of codes. Normally, paid users are regarded serious users and will not add wrong codes intentionally.
5. Q: Does UMCS have duplicated codes?
A: Duplicated codes cases can be divided into two kinds.
The first kind of cases is "one code to multi-items", that means a material code refers to many material items. In UMCS, this case does not exist. Each material
code has clearly-defined name and specifications.
The second kind of cases is "Multi-codes to one material item", that means one material has more than one codes. In engineering practice, there are different names or specifications for one material. Because the material code is based on a set of material name and specifications, there may be some different codes referring to same material.
The second case does not affect the user because of the following reasons. First, user can select one material code for a certain material if there are different codes for this material. Second, "Multi-codes to one material item" does not mean wrong code, they are only different referring to material. At last, the user can report this case to the UMCS administrator to correct this case.
6. Q: How to deal with wrong information that is input by user carelessly ?
A: As a highly open and user-generate-content coding system, UMCS doses not judge the correctness of information input by user. If the user find that he has input wrong information, never mind. Do not use the material code of wrong information. User can inform the administrator of UMCS, they will mark the wrong code as invalid code.
7. Q: Our company has overseas project. Is there English Version for UMCS?
A: UMCS has 2 versions, Chinese version and English version. The English version web site is www.e-umc.com. The material code in UMCS is based on the language. Even same materials, which are described by different language, have different codes. UMCS suggests user to find correct material in their working language.
Other language version will be on-line in future.
